The question states angles A and B are vertical angles, which makes them equal to each other. So if angle A equals 22°, angle B also equals 22°.

Question

Then you need to think about complementary angles (2 angles that add up to be 90°). If angles B and C are complementary this means angle B + angle C = 90°. From here you need to write an equation that would help you solve for angle C.

Answer 1

Angle A = 22°
Angle B = 22°
Angle C = ?

Since angles B and C are complementary, we can write the equation:
Angle B + Angle C = 90°

Substitute the values we know:
22° + Angle C = 90°

Now, solve for Angle C:
Angle C = 90° - 22°
Angle C = 68°

Therefore, Angle C = 68°.
