Question

P,W,R & S form the vertices of a quadrilateral. PQR = 74 degrees

RSP = 121 degrees
Find the value of SPQ

Answer 1

∠ SPQ = 75°

Explanation:

The sum of the 4 angles in a quadrilateral = 360°

Subtract the sum of the 3 angles from 360 for ∠ SPQ

∠ SPQ = 360° - (90 + 74 + 121)° = 360° - 285° = 75°
