Question

One base angle of an isosceles
triangle is 63.5. What is the
measure of the vertex angle?

Answer 1

Answer:

53 degrees

Step-by-step explanation:

1) Base angle- 63.5 degrees: Given

2) Other base angle is- 63.5 degrees: Base Angle Theorem

3) Sum of angles in triangle: 2(63.5)= 127

180-127= 53

53 degrees
