If one of the exterior angles is 40, you can find its adjacent interior angle by subtracting 40 from 180. This is 40, so the triangle has 2 interior angles that are equal to 40. Now we have 2 of 3 interior angles. The sum of the measures of the interior angles of a triangle is 180, so we can set this equation up:
x + 40 + 40 = 180
x + 80 = 180
x = 100
So the triangle's angles have measures of 40,40 and 100 degrees.
Answer:
80
Step-by-step explanation:
Answer:
x = - 45
Step-by-step explanation:
x+23(-23)=−22 (-23)First subtract 23 from both sides
x = - 45
B pretty sure that it’s that
