Question

two angles of a triangle are equal and the exterior angle measures 110 degree find the angle x​

Answer 1

Exterior angle = 110°

Then, opposite interior angle will be equal to 180-110 = 70°

Now, lets assume other two equal interior angles be x and x, then

x+ x+ 70 = 180

2x = 180-70

2x = 110

x = 55

Therefore, All interior angles are 55°, 55° and 70°

Answer 2

Answer:

55°

Step-by-step explanation:

we know,

exterior angle is equal to sum of two opposite interior angles.

110 = x + x

2x = 110

x = 55°
