50 points so Quick answer please, thank you.

Answer: x = 81 degrees, y = 68 degrees, z = 99 degrees
Step by step:
Use fact that angles sum up to 180 degrees in any triangle.
Left triangle:
180=36+63+x
x = 180-99 = 81 degrees
Use the fact that x and z are supplementary angles:
180 = x + z = 81 + z
z = 180 - 81 = 99 degrees
And again using triangle angle sum of 180 degree:
180 = 13 + z + y = 13 + 99 + y
y = 180 -112 = 68 degrees
Answer:
Step-by-step explanation:
Since triangles have a total degree count of 180 degrees you would subtract 36 + 63 which equals 99 from 180 which would be 81 so
x= 81 degrees
A flat line is also equal to 180 degrees so you subtract 81 (x) from 180 to get 99, so
z=99 degrees
You repeat the beginning process and do 13 + 99 which equals 112 and subtract it from 180 which is 68, so
y=68 degrees
