Question

In the given figure <ABC side Ac has been produced to D.<BCD = 125 and CA:CB#2:3, find the measure of angle angle A and angle B​

Answer 1

Answer:

Let ∠A=2x and ∠B=3x

∠BCD=∠B+∠A (Sum of exterior angle of triangle is equal to sum of two opposite interior angles )

2x+3x=125∘

5x=125∘

x= 125/5∘

=25∘

∠A=2x=2×25∘

=50∘

∠B=3×25∘

=75∘
