The answer is 15.8 Hope it helps
y = 46°
This is because alternate angles are equal so y is equal to 46°.
x = 54°
We first need to find the other angle inside the triangle by adding 46 and 54 to get 100, and then subtracting that from 180 to get 80 as angles on a straight line add to 180°.
Then we can add 80 and 46 to get 126, and subtract 126 from 180 to get 54, as angles in a triangle add to 180°.
w = 126°
This is because angles on a straight line add to 180°, so we need to subtract 54 from 180 to get 126.
z = 148°
This is because you first find the co-interior angle above z by doing 180 - 32 = 148 as co-interior angles add to 180°. This angle is then vertically opposite to z, which makes it equal to z.

First, we’re going to use this formula:
2nd number - 1st number
————————————— x 100%
1st number
If we plug in the numbers to this equation:
23-20
———- x 100%
20
And subtract 23 to 20, the answer to this equation is:
3
—- x 100% = 15%
20
In this case, the percent of increase is 15%.
