Question

In a given triangle, one interior angle is 80 degree. Calculate the second interior angle x degree​

Answer 1

Answer:

Value of x is 65°.

Step-by-step explanation:

We know that

Exterior Angle = Sum of two angles opposite to the exterior angle

Here, 145° = 80° + x°

=> x° = (145 – 80)°

=> x° = 65°

Thus value of x is 65°.
