Answer:
70
Explanation:
The non-labeled side (next to 130) has to be supplementary to the angle outside, hence it has to be 50. Since all the sides of an angle must add up to 180, we can subtract 60+50 to get 70. Hope this helps!
70°
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.
130 = x + 60
x = 70
Answer: 70°
