ASAP HELP!!! I'm really confused.

Answers

Answer 1

Answer:

m2KJL = 54°

Step-by-step explanation:

In AJKL,

MAJKL = 72°

JK = KL

Since, two sides of AJKL are congruent, triangle is an isosceles triangle.

By the property of an isosceles triangle,

Opposite angles of the congruent sides of an isosceles triangle are equal in measure.

Therefore, J = ZL

By the property of a triangle,

Sum of all interior angles of a triangle is 180°.

m2J + m2K + m2L = 180°

mzJ + 72° + mzJ = 180° [Since, mzJ = mzL]

2mzJ = 180° - 72°

mzJ = 54°

Therefore, mZKJL or mzJ is 54°.

Answer:

4n + 1

Step-by-step explanation: The numbers are rising by 4, so this gives us 4n. Term number 1: 4n = 4, but the first number in the sequence is 5 so we have to add 1.

Term number 2: 4n = 8, but the second number in the sequence is 9 so, again, we have to add 1.

What is hydropower? And how does it work? (2-3 sentences Is good enough) thx :3

WILL MARK BRAINLIEST WHOEVER ANSWERS FIRST:DDD!!

Answers

hydropower or water power is power derived from the energy of falling or fast- running water
And it work by Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

Answer:

Hydropower is a form of renewable energy. Water will spin a turbine, which will then generate electricity.

What is the point-slope form of a line?

If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).

(a)

The table of values is given.

Rewrite the table of values as ordered pairs:

(5,108), (10,88), (15,68)

Since the difference between any two consecutive y values and the difference between any two consecutive x values is constant, the data shows a linear relation.

The slope of the line that passes through (5,108) and (10,88) is:

m = (88-108)/(10-5)

m = -4

The equation of the line with slope m = -4 and passes through (5,108) is:

y - 108 = -4(x - 5)

y = -4x + 20 + 108

y = -4x + 128 (1)

(b)

Substitute x = 0into equation (1):

y = - 4(0) + 128

y = 128

The tank is 128 ounces cleaner at the beginning.

(c)

Substitute y = 0 into equation (1):

0 = -4x + 128

4x = 128

x = 32

Therefore, the tank will be empty in 32 minutes.

56 is 28% of an unknown number is (x)

Answers

Answer:

Change 28% to a decimal by moving the decimal point 2 places to the left:

28% = 0.28

Write the question as an equation to get:

56 = 0.28x

Now to solve for x, divide both sides by 0.28:

x = 56 / 0.28

x = 200

The unknown number is 200.

Step-by-step explanation:

28% of an unknown number is (x)=56

28/100 of x=56

x=56×100/28=200

(Sat Prep) Find the value of x)

Answers

Answer:

1. x = 120°

2. x = 115°

Step-by-step explanation:

For the first question, you can see that the two lines are parallel. This means you can use any of the alternate interior angles, alternate exterior angles, corresponding angles, consecutive interior angles, and consecutive exterior angles.

You can see that the transversal cutting the two parallel lines make a 40° angle, and through alternate interior angles, the angle next to x is also 40°.

Because a straight line is 180°, the three angles that make up the straight line will add up to 180°. So:

x + 20° + 40° = 180°

x + 60° = 180°

x = 120°

For the second question, extend the line (the left one marked with 1 arrow) to make a smaller triangle attached to the parallelogram.

Because this is a parallelogram, opposite angles are congruent. So the opposite angle of x is also x.

Straight lines are 180°, so 180 - x will be what the angle measure is. If this is too confusing, refer to the image below.

Those two angles, 50° and (180 - x)°, will add up to be the exterior angle, which is also x.

So:

50 + 180 - x = x

230 = 2x

115 = x

x = 115
