Question

an exterior angle of a triangle is 115° and its two interior opposite angles are equal .each of these angles is​

Answer 1

Answer:

Since exterior angle of a triangle = Sum of opposite interior angles.... Hence two angles of a triangle is 57.5°. =) ... Hence angles of a triangle are 57.5°, 57.5° and 65°.

Hope it helps you!!!

Answer 2

Answer:

The measure of each angle is 57.5°.

Step-by-step explanation:

We know,

Exterior angle of a triangle = sum of the interior opposite angles

(By Exterior Angle Property)

Let each of the interior angles be x.

⇒ 115° = x + x

⇒ 115° = 2x

⇒ 57.5° = x

Therefore, x = 57.5°.
