Answer:
A. ∠c=126°
B.∠x=∠z=130° & ∠y=50°
Step-by-step explanation:
→A.
as ∠POY=90°
2x+3x=90°
5x=90°
x=18°
hence ∠a=18 × 2 =36°
∠b=18 × 3 =54° [Total ∠a+∠b+90=180 as XY=90°]
∠XOM=∠B=54°=∠NOY [vertically opposite angles]
Therefore as XOY is a straight line total ange is 180°
hence ∠XON =∠c=180-54=126°
→B.
∠POS=∠ROQ=50° [vertically opposite angles]
and,∠SOQ=180-50=130°
Hence ∠POR=∠SOQ=130° [vertically opposite angles]
→Therefore your answers are A. ∠c=126°
B.∠x=∠z=130° & ∠y=50°
