Question

(question in the in image above the other side if angle Q is 113

Find x​

Answer 1

x = 85

Explanation:

the exterior angles of a polygon sum to 360°

note the exterior angle at P = 180° - 90° = 90°

sum the 4 exterior angles and equate to 360

x + 72 + 113 + 90 = 360

x + 275 = 360 ( subtract 275 from both sides )

x = 85
