Question

An exterior angle of a triangle is of measure 70 degree and one of its interior opposite angles is of measure 25 degree. find the measure of the other two interior angle​

Answer 1

Answer:

45°

Step-by-step explanation:

Given :

Exterior angle of triangle = 70°

One of its interior opposite angles = 25°

So Let, the other interior angle of triangle be x.

According to Exterior Angle Property of triangles,

The sum of the two opposite interior angles of triangles is equal the measure of exterior angle.

So,

25° + x° = 70°

 x° = 70° - 25°

 x = 45°

Hence, The other interior angle is 45°
