∠a and ∠b are complementary angles. ∠a measures 22°.

what is the measure of ∠b?

​

∠b = 68°

Step-by-step explanation:

Complementary angles are a pair of angles that, added together, equal 90°.

If ∠a = 22°, then the measure of∠b must equal 90° when added to that of ∠a.

To find the measure of ∠b, then, we can subtract ∠a from 90°.

90 - 22 = 68

The measure of ∠b, then, is 68°.

I hope this is helpful ^^

Good luck

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.
