Question

In Δ ABC, mC = 3 mB = 2 (mA + mB). Then find the measures of all three angles.

Friends pls attach the pics of the solutions​

Answer 1

Step-by-step explanation:

mC = 3mB. => C = 3B

3mB = 2mA + 2mB => A = 0.5B

in a triangle, A+B+C=180

0.5B+B+3B=180

4.5B=180

B=40

A=0.5x40=20

C=3x40=120
