Question

The sum of the measures of the three angles is equal to 180 degrees. What is the measure of angle B?

The angle measures of a triangle are shown

Angle A: (5x - 5) degrees

Angle B: (3x + 3) degrees

Angle C: (5x) degrees

Answer 1

Answer:45°

Explanation:

First we need to find x

(5x-5)+(3x+3)+(5x)=180

Simplify

13x-2=180

Add 2 to each side

13x=182

Divide each side by 13

x=14

Now apply our x to angle B

3(14)+3

42+3

45

Angle B=45°
