Answer:
x = 10
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, thus
∠ A + ∠ B = 180, substitute values
9x + 8 + 8x + 2 = 180, that is
17x + 10 = 180 ( subtract 10 from both sides )
17x = 170 ( divide both sides by 17 )
x = 10
Answer:
the answer is 4-x^2
Step-by-step explanation:
-2x
and 2x cancel out
First replace y with 15.
1/5x-10=30
Then just solve from there.
x=200
