<u>Answer</u>:
Angle A = 17°, Angle B = 73°
<u>Step-by-step explanation:</u>
Angle A & Angle B are complementary angles (given) so they will form 90°.
Let's take,
Angle A = x
Angle B = 4x +5 (angle B is five degrees more than four times angle A)
Measure of each angle=?
Angle A + Angle B = 90°
x + 4x + 5 = 90
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85 ÷ 5
x = <u>1</u><u>7</u><u>°</u>
Angle A = x = <u>1</u><u>7</u><u>°</u>
Angle B = 4x + 5 = 4(17) + 5 = 68 + 5 = <u>7</u><u>3</u><u>°</u>

Answer:
Step-by-step explanation:
You don't know the number, so you replace it with x.
Since it is one third of x, you multiply x by 
Then you subtract 5 from the whole thing:
