Question

R N Q 45 45 9. ZQZR is a straight angle. What is the measure of OZS? ABCDE A. 45 B. C. D. S E. 60° 90° 125° 135°

how to solve this?​

Answer 1

Answer:

E

Step-by-step explanation:

the angles lying on the straight angle QZR , sum to 180° , then

∠ RZS + ∠ QZS = 180° , that is

45° + ∠ QZS = 180° ( subtract 45° from both sides )

∠ QZS = 135°
