Question

HELP PLEASEEEEE!!!!!

Answer 1

C) 29

Explanation:

All triangles add up to 180 degrees,

subtract the known 59 from 180 to get 121.

then combine (3x) and (x + 5) to get 4x + 5

4x + 5 = 121 solve

4x = 116

x = 29

Answer 2

x = 29

Explanation:

Sum of interior angles of a triangle = 180°

⇒ 59 + 3x + x + 5 = 180

⇒ 4x + 64 = 180

⇒ 4x = 116

⇒ x = 29
