Question

If ∆ABC~∆DEF,angle B =60° and angle C=50°,find the measure of angle D

Answer 1

Answer:

70°

Step-by-step explanation:

Since both the triangle are similar all the angles will be equal

angle B=angle E=60°

angle C=angle F=50°

By angle sum property

angle (D+E+F)=180°

60+50+angle D=180

Angle D=70°
