using pythagorean theorm
now we find the side without a variable will call it z
now we use cos to find the angle then we use that to find the other angles and find our sides
in short the angle at the top right between y and z is 36.869897645844
and the x and y angle is 53.13010235 (SOH CAH) is what i used
using our angles we can find the sides now
and using pythagorean theorm we get that
simplfiy and we get that 8=x
