Question

Anybody want to help me with this math problem? Finding an angle measure for a triangle with an extended side.

Answer 1

Explanation:

Answer 2

x = 130

Explanation:

Angles in a triangle add up to 180:

57 + 73 = 130

180 - 130 = 50

Angles in a straight line add up to 180:

180 - 50 = 130

so x = 130
