Question

In rectangle READ, find the measure of ∠EAR, ∠RAD and ∠ROD.​

Answer 1

Answer:

Given , ∠ ROE = 60

Here,

∠ AOE = 120,∠ AOD = 60 and $$ \angle \,ROD = 120 $$

In triangle AOE , consider ∠ EAR = ∠ DEA = x

x + x + 120 = 180

2x + 120 = 180

2x = 60

x = 30 , i.e., ∠EAR = 30

In triangle AOD , consider ∠RAD, = ∠EDA = y

∠RAD + ∠EAR + ∠AOD = 180

y + y + 60 = 180

2y = 120

y = 60

∠RAD, =∠EDA = 60°
