Question

please can somr one help me​

Answer 1

Answer:

The angle be x

so,

x+x=150°(exterior angle property)

2x=150

x=150/2

x=75°

Now angle A =angle C

so A=75,C=75 and B=?

let's find the angle b

we know that the sum of three side of angle is 180°..so,

angle A+angle B +angle C=180°

75°+75°+angle B=180°

150°+angle B=180°

Angle 'B'=180°-150°

Angle B=30°

Hence the three sides are

A=75°,B=30° and angle C=75°
