X is the undefined variable hope it helps
x + 2y = 9
x + 3y = 13
____________________________________________________________
Solve for x in the first equation. Subtract 2y from both sides.
x = 9 - 2y
____________________________________________________________
Plug x into the second equation.
(9 - 2y) + 3y = 13
Combine like terms.
9 + y = 13
Subtract 9 from both sides.
y = 4
____________________________________________________________
Plug y back into the first equation.
x + 2(4) = 9
x + 8 = 9
Subtract 8 from both sides.
x = 1
____________________________________________________________
x = 1
y = 4

Answer:
152°
Step-by-step explanation:
If two pairs of congruent angles total 360°, then the different angles must total 180°. The other angle measure is 180° -28° = 152°.
The measure of each angle in the other congruent pair is 152°.
You would change 30 percent to a decimal, so .3 is your multiplyer
