Answer:

  • x = 11
  • y = 4

Step-by-step explanation:

In order to solve this, we need to assume that the angles involving x are supplementary, and the angles involving y are complementary.

  (7x -8) +(13x -32) = 180

  20x -40 = 180 . . . . . . . . . collect terms

  20x = 220 . . . . . . . . . add 40

  x = 11 . . . . . . . . . . divide by 20

__

  (10y +22) +(7y) = 90

  17y = 68 . . . . . . . . . . . . collect terms, subtract 22

  y = 4 . . . . . . . . . . divide by 17

First, subtract to get the difference.
2.85 – 2.78 = 0.07

Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).

Hope this helps!
