Step-by-step explanation:
let the angle be x
20+4x+x=180
20+5x=180
5x=160
x=32
So, the question is 63 is 30% of what number?
That can translate to the equation
63 = 30% · x or 63 = 0.3x
Divide by 0.3 and you get x = 210.

Multiply first formula by 2, then do formula 1-formula 2
(2, 5) and (5, 8) are the solutions to the system of equations.
We have
and
.
Let's substitute
for
in
. We get
. Now, factor to solve for
.
Now, substitute each value of
into one of the original equations to solve for
.
