Answer:
x = 81, y = 68, z = 99
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left, then
x = 180 - (36 + 63) = 180 - 99 = 81
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle on the right, thus
13 + y = x , that is
13 + y = 81 ( subtract 13 from both sides )
y = 68
Consider the triangle on the right
z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99
7x + 1
Combine like terms: 2x + 5x
Then add the remaining terms: 7x + 1

The middle point aka the E has to be in the middle and then the first and last points don’t matter
So 2/3 as a decimal would be 0.66 and 7/8 as a decimal would be 0.125 so if you subtract the 2 decimals it would give you the answer of 49 slices.
i hope i'm right! :)
