If ∆ABC ~ ∆ DEF and angle A=30°; AngleB = 50° then Angle E + Angle F is equal to ____​

Answer»

Answer:

150°

Step-by-step EXPLANATION:

Given,

∆ABC~∆DEF, then:

In∆ABC and ∆DEF,

ANGLE A = Angle D = 30°

Angle B = Angle E = 50°

Angle C = Angle F = {180°-(30°+50°)} =100°

(By angle SUM PROPERTY of ∆)

therefore,

Angle E + Angle F = 100°+50°=150°
