Question

2.) Find the measure of exterior angle X:

Answer 1

ANSWER:
try 110 , sorry if that’s wrong

Answer 2

Answer:

x = 90

Step-by-step explanation:

Here 60 is angle B, 30 is Angle a, B is The third angle of the triangle, and x is the exterior angle measurement!

60 + 30 + b= 180

a + x = 180

60 + 30 + b= 180

90 + b = 180

b = 90

90 + x = 180

x = 90

Note:

exterior angle  equal to the sum of its two opposite non-adjacent interior angles.
