Find angles x and y.
First list some equations. (x-3) + 41+ (y+8) = 180
(x-3) = 74
Now we have some equations to work with.
74 + 41 + y + 8 = 180
y + 123 = 180
y = 57
Now plug y into the main equation.
x - 3 + 41 + 57 + 8 = 180
x + 103 = 180
x = -77
(x - 3) = 74
x = 77
(y + 8) + 41 + (x - 3) = 180
(y + 8) + 41 + 74 = 180
y = 180 - 8 - 41 - 74
