Answer 2

Answer:

The sum of all three angles in any plane triangle is 180 degrees.

Therefore we see that:

A + B + C = 180

B=3A

C=A +120°

Thus:

A + 3A + A + 120=180

5A+120=180

5A=180-120

5A=60

A=60/5

A=12°

B=3×12

=36°C

= 12+120

=132°

To check add A + B + C = 12+ 36 + 132 = 180° degrees.
