Question

state and prove angle sum property of ∆. Hence solve for the is of ∆ if teo angles are in ratio 2:3 and third angles is of 30degree​

Answer 1

Answer:

Let angle be x

Given

Two angles ratio is 2:3

Third angle is 30degree

2x+3x+30=180

5x=180-30

5x=150

x=150/5

x=30

2x=2×30

=60

3x=3×30

=90
