toal is 180 lol 2 of the triangles are the same size

2*56+x=180

Answer 4

okat> what i do next?

Answer 5

those two angles you are looking for are opposite of congruent sides, so those two angles are equal to each other.

A triangle has 3 angles that add up to 180, so

180 - 56 = 124

Answer 6

solve for x

Answer 7

Now divide 124 by 2 and you have the measure of each angle

Answer 8

62
