Question

Use the TriangleAngle-Sum Theorem to answer the following questions.Explain your answers.a. What are the measures of each angle of an equiangular triangle?b. If one of the angle measures of an isosceles triangle is 90°, what are themeasures of the other two angles?

Answer 1

45 degree

Explanation:

the sum of a triangle is 180

a+b+c=180

since two side of a isosceles triangle is equal

let the unknown be x

90+x+x=180

collet like term

2x=180-90

2x=90

divide both sides by 2

x=90\2

x=45
