Use the Pythagorean Theorem:
a² + b² = c²
4² + b² = 8.5²
16 + b² = 72.25
b² = 56.25
b = 7.5

Answer:
34, 56 . . . . degrees
Step-by-step explanation:
Let x represent the smaller angle. Then x+22 is the larger. Complementary angles have a sum of 90°:
(x)° +(x +22)° = 90°
2x = 68
x = 34
x +22 = 56
The two angle measures are 34° and 56°.
