Answer:

see explanation

Step-by-step explanation:

Supplementary angles sum to 180° , then

x + y = 180 , that is

$\frac{1}{3}$ y + y = 180 ( multiply through by 3 to clear the fraction )

y + 3y = 540

4y = 540 ( divide both sides by 4 )

y = 135°

Solve for B. <br><br> A = 3(B + C)

Vanyuwa [196]

This is a literal equation
first, divide 3 on both sides $\frac{A}{3} = \frac{3(B+C)}{3}$
Next, subtract C on both sides $\frac{A}{3} -C=B+C-C$

The answer is $B= \frac{A}{3} -C$
