Question

in the figure PQ⊥QS find x and y where angle PRS=120° and angle PSR=30°​

Answer 1

Answer:

x = 30°

y = 30°

Step-by-step explanation:

In triangle PRS,

Sum of all interior angles =180 degrees

=> x+120+30 =180 =>x =180-150 =>x= 30 degrees

angle PRS is an external angle to the triangle QPR.

Exterior angle is equal to sum of interior opposite angles

y+90 =120

=>y =30 degrees
