Question

C. Find the value of X. Show your work. Congruent triangles

Answer 1

Explanation:

1) 97 + x = 64 + 27 {Exterior angle property}

97 + x = 91

x = 91 - 97

x = -6

2) 4x + 17 + 80 + x + 23 = 180 {Angle sum property of triangle}

4x + x + 17 +80 + 23 = 180

5x + 140 = 180

5x = 180 - 140

5x = 40

x = 40/5

x = 8
