Question

One of the exterior angle of a BC measure 150 degree of if one of the intricate positive angle is 75 degree find the other interior opposite angle what type of triangle is this

Answer 1

Answer:

Other Interior angle = 75°

It is an isosceles triangle

Step-by-step explanation:

External angle = Sum of 2 interior opposite angles

Let the other angle be x

150° = 75° + x

x = 150° - 75°

x = 75°

Therefore, the other Interior opposite angle = 75°

Since, 2 angles of a triangle are equal, it means that 2 sides of the triangle are also equal. Hence, it's an isosceles triangle.
