Answer:

The interior angles of any triangle equal 180. Triangle CDF is an equilateral triangle meaning all of its angles are the same. 180/3=60

Each angle of triangle CDF is 60

1.m<CDF=60

____________________________________________________________

Isosceles triangles have the 2 base angles the same value while the other angle is another value. IN that instance, the m<a = m<f and the m<a + m<f +  m<b=180°

If we find one of the angles of ABF then we can find all of them.

the m<AFB + 35° + m<CFD + m<DFE=180°

we know that the m<CFD is 60

35+60+m<AFB + m<DFE=180

95+m<AFB + m<DFE=180

LEts look at the angle AFD

AFD is 150° and since m<AFD and the m<DFE are supplementary, the angle of DFE is 30

lets test it:

if m<DFE is 30 then

95+m<AFB + 30=180

125+m<AFB=180

m<AFB=55

therefore the m<BAF would also be 55 and the m<ABF would be 70

m<ABF=70

This is because the interior angles of any triangle add up to 180°

I hope this helps and please let me know if i was incorrect

Answer:

for X its 90 degrees

Step-by-step explanation:

If its a right angle it is 90 degrees

Answer:

x=16

y=27.7

Step-by-step explanation:

In a 30-60 right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.

x is the side opposite the 30 degree

so x=32/2=16

let's use pythagorean theorem to find y

x^2+y^2=32^2

y^2=32^2-x^2

y^2=1024-16^2

y^2=1024-256

y^2=768

y=√768

y=27.7

Answer:

Infinitely many solutions.

Step-by-step explanation:

x-2(x-6)= -x+12

x - 2x + 12 = -x + 12

x - 2x + x = 12 - 12

0 = 0.

This means there are infinitely many solution.

Cost of 40 pounds of apples at David's apple is $50.

Cost of 40 pounds of apples at Pam's orchards is $37.5.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Anna want to pick 40 pounds of apples,

Now, At David's apple orchard cost of first 10 pounds = $2 per pound

And, Each additional pounds $1 per pound.

So, Cost of 40 pounds of apples at David's apple is calculated as;

Cost of first 10 pounds = 10 * 2 = $20

And, Cost of 30 pounds of additional apples = 30 * 1 = $30

Hence, Cost of 40 pounds of apples at David's apple = $20 + $30

                                                                                  = $50

At Pam's orchards first cost of first 10 pounds = $1.50

And, Each additional pounds $0.75 per pound.

So, Cost of 40 pounds of apples at Pam's orchards is calculated as;

Cost of first 10 pounds = 10 * 1.50 = $15

And, Cost of 30 pounds of additional apples = 30 * 0.75 = $22.5

Hence,  Cost of 40 pounds of apples at Pam's orchards = $15 + $22.5

                                                                                      = $37.5

Therefore,

Cost of 40 pounds of apples at David's apple is $50.

Cost of 40 pounds of apples at Pam's orchards is $37.5.

Answer:

x = 3.6

Step-by-step explanation:

8 + x = 3.5x - 1

x - 3.5x = -1 - 8

-2.5x = -9

x = 3.6

Answer:

x = 3.6

Step-by-step explanation:

8 + x = 3.5x - 1

subtract 8 from both sides

x = 3.5x - 9

subtract 3.5x from both sides

-2.5x = -9

divide by -2.5 from both sides

x = 3.6

Step-by-step explanation:

Answer:

118

Step-by-step explanation:

you can look at the 62° it is straight line to (2y).

And the left angle of 62°, let it be 'x' . Can be measured by [ x + 62° = 180°]

[x = 180° - 62° ]

( x = 118° )

Then, A is the alternate angle of x . so, the value of A is 118.. The reason is being alternate angle.

Step-by-step explanation:

Answer:

k = 4

Step-by-step explanation:

A perpendicular bisector is defined as a line or a line segment that divides a given line segment into two parts of equal measurement.

So WX = XY or WX = 1/2 WY

using WX = 7k + 5 and WY = 66

7k + 5 = 66/2

7k = 33 - 5

7k = 28

k = 4

0.60 = x/100

0.60 * 100 = x

60 = x

25 * 60% = 15

Answer:

x=  1.13 or x= -1.45

Step-by-step explanation:

use the quadratic square root formula (-b±√(b²-4ac))/(2a) .

a= 3

b=1

c= -5

replace the variables with the numbers listed above and just work out.

x=  1.13 or x= -1.45

Answer:

x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61

Step-by-step explanation:

3x^2+x-5=0

Using quadratic formula a=3, b=1, c=-5

x = -b ± √b^2 - 4ac / 2a

x = -(1) ± √(1)^2 - 4(3)(-5) / 2(3)

x = -1 ± √61 / 6

x = -1/6 + 1/6√61 or x = -1/6 + -1/6 √61

Answer:

f(x) = (x+10)^2 - 4

Step-by-step explanation:

vertex form is y = a(x-h)^2+k

to complete the square, we want to add a number on both sides so x^2+20x+whatver the number is, is the square of something

to find that number take 20, divide by 2, and then square it to get 100.

so, you would get f(x)+100 = x^2+20x+100+96

subtract 96 on both sides: x^2+20x+100 = f(x) + 4

factor: f(x) = (x+10)^2 - 4

Answer:

x = 4

Step-by-step explanation:

x^2 - 8x = -16

Add 16 to both sides.

x^2  8x + 16 = 0

This may be the square of a binomial.

x^2 is the square of x

16 is the square of 4 and -4.

Let's check the middle term:

2ab = 2(x)(-4) = -8x

Yes, it is the square of a binomial.

x^2 - 8x + 16 = 0

(x - 4)^2 = 0

x - 4 = 0 or x - 4 = 0

x = 4 or x = 4

Answer:

61 ft

Step-by-step explanation:

I'm assuming that the diver simply walked off the cliff since we were not given any information about the jump itself.

If the distance between the cliff and the surface of the water is 48.5 feet, and if the distance between the surface of the water and the place where the diver stopped descending is 12.5 feet, you would add those two distances up.

48.5 ft + 12.5 ft = 61 ft

The total distance of her jump from her was 61 feet.

Given that a diver jumps from a cliff that is 48.5 feet above the surface of the water, and she stops descending 12.5 feet under the water, to determine what was the total distance of her jump, the following calculation must be performed:

The height of the cliff and the depth at which it reached under the water must be added.

Therefore, the total distance of her jump from her was 61 feet.

Answer:

-3x + 40

Step-by-step explanation:

The constant given is 40 gallons and the rate at which the water in the bathtub decreases is 3 gallons per minute.

To write this as an equation we model 40 as the starting constant that is positive and, because the water is decreasing, we use a negative slope.

-3x represents the decrease in water over x intervals (Which in this case is minutes) and 40 gallons represent the initial value (water in the bathtub).

Therefore the water in the bathtub can be modeled with the equation

-3x + 40
