Question

an exterior angle of a triangle is 115 and it's two interior opposite angles are equal then find the measure of each equal angle.

Answer 1

let the two equal angles be x

now,
2x=115 (exterior angle theorem of triangles)

=x=57.5degree

so both the equal angles are 57.5 degree

Answer 2

Answer:

57.5

Step-by-step explanation:

Let equal angles be x

As from extrior angle property that sum of interior opposite angles is equal to exterior angle

2x=115

x=115/2

x=57.5
