Question

21. Find the value of x and y.​

Answer 1

Answer:

x = 50°

y = 80°

Step-by-step explanation:

ΔQTR has 90° and 40°.

∴ ∠x = {180 - (90 + 40)}° = (180 - 130)° = 50°

ΔPTO(the center point) has 30° and 90°

∴ ∠O = {180 - (30 + 90)}° = (180 - 120)° = 60°

∴ ΔQOS will have 40°,  60° and y

40 + 60 + y = 180°

∴ y = {180 - (40 + 60)}° = (180 - 100)° = 80°
