Question

The equation a + b + c = 180 describes the sum of the angles in a triangle.

Use this formula to find the values of a, b and c when b = 2a and c = 3a​

Answer 1

a=30 b=60 c=90

Explanation:

you replace b with 2a and c with 3a and you get

a+2a+3a=180

6a=180

a=30

from here you replace a with 30 and find b and c

b=2a=2*30=60

c=3a=3*30=90
