Question

∆ABC ~ ∆DEF and <A+<B =140° then find <F​

Answer 1

Answer:

40°

Step-by-step explanation:

since ∆ ABC~∆ DEF this ∆ ABC & ∆ DEF are equiangular

angleC= angleF= 180-(angleA+angleB)

180-140= 40

Answer 2

Answer:

40° .

Since ∆ ABC ~ ∆ DEF this , ∆ ABC & ∆ DEF are equiangular.

Angle C = Angle F = 180° - ( Angle A + Angle B )

(180 - 140)° = 40°
