Because if x is greater than y, then x-y wouldn’t be below 0 like it’s shown, so x must be less than y.

And if x is less than y, any negative y would mean x is negative as well since it’s always less than y. And as shown, x+y is positive so it’s impossible for y to be negative.

1) One angle is 28° larger than the other. The sum of the measures of two angles is 90°. Find the measure of each angle.
X=_____
Equation:______​

Answers

Answer:

62

Step-by-step explanation:

Equation: x +28 =90

x = 59°

Measure of one angle = 59°

Measure of another angle = 31°

Equation to calculate the measurement: x + x - 28 = 90Given,

What is angle?

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.

Given,

Sum of two angles = 90°

One angle is 28° larger than other

Let the measurement of one angle is x

then other angle = x - 28°

But,

x +  x - 28° = 90°

2x - 28° = 90°

2x = 90° + 28°

x = 118°/2

x = 59°

one angle = 59°

other angle = 59° - 28° = 31°

Hence, 59° is measure of one angle

and 31° is measure of other angle.

x + x - 28 = 90 is the Equation to calculate the measurement.

Which equation represents a line that has a slope of 1/3 and passes through point (-2,1)?

Answers

Answer:

The equation would be y - 1 = 1/3(x + 2)

Step-by-step explanation:

In order to find this, we simply plug the values we have into point slope form.

y - y1 = m(x - x1)

y - 1 = 1/3(x - -2)

y - 1 = 1/3(x + 2)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Slope = m = 1/3

(-2 , 1)

[tex]y - y_{1}= m(x - x_{1})\\y - 1 = \dfrac{1}{3}(x -[-2] )\\\\y - 1 = \dfrac{1}{3}(x + 2)\\\\y - 1 =\dfrac{1}{3}x + \dfrac{1}{3}*2\\\\y=\dfrac{1}{3}x+\dfrac{2}{3}+1\\\\y=\dfrac{1}{3}x +\dfrac{2}{3}+\dfrac{3}{3}\\\\y=\dfrac{1}{3}x +\dfrac{5}{3}[/tex]

D is on side AB of triangle ABC. We know triangle ABC ~ triangle ACD and angle A = 48 degrees. If BC = CD what is angle B in degrees

Answers

Answer:4/6

Step-by-step explanation:

The measure of angle ∠B will be 66 degrees.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

D is on side AB of triangle ABC. We know triangle ABC is similar to triangle ACD and angle A = 48 degrees. If BC = CD.

∠ABC = ∠ACB = x (Isosceles triangle property)

In △ABC, the angle sum is 180°. Then we have

∠ABC + ∠ACB + ∠ABC = 180°

x + x + 48° = 180°

2x = 132°

x = 66°

Then

∠BCA = ∠BCD + ∠DCB = 66°

∠BCD = 66° − 18°

∠BCD = 48°

Now, In ΔBCD, then we have

∠BCD + ∠BDC + ∠DBC = 180°

48° + ∠BDC + 66° = 180°

∠BDC = 66°

We know that ∠BDC = ∠DBC,

∠DBC = ∠BDC

∠DBC = 66°

The measure of angle ∠B will be 66 degrees.
