Z = √(10^2 + 8^2 - 2 *10 * 8 * cos(z)
z = arccos(1/8
A = 82.8

Answer:
x = 53°
y = 90°
Step-by-step explanation:
We can see that angle y is a right angle, so y is 90°.
The marked red line above may be a straight line, so x+37° = 90, because the marked orange line is perpendicular to the red line (y=90°).
x + 37° = 90
x = 53°
