Question

In a triangle ABC A=2B and A=1/3 C fimd all measures all three angles
​

Answer 1

Answer:

We know that in a △, the sum of all the interior angles is 180

∘

⇒∠A+∠B+∠C=180

∘

........(1)

Also given that,

∠C=3∠B and 3∠B=2∠A+2∠B

∠A=

2

∠B

Substituting values in (1), we get

2

∠B

+∠B+3∠B=180

∘

∴∠B=40

∘

∠A=20

∘

∠C=120
