Question

An angle measures 87.6° less than the measure of its complementary angle. What is the measure of each angle?

Answer 1

1.2°, 88.8°

Explanation:

let one angle=x

other angle=y

y=x-87.6

also

x+y=90

x+x-87.6=90

2x=90+87.6=177.6

x=88.8

other angle=88.8-87.6=1.2

Answer 2

1.2° and 88.8°

Explanation:

Complementary angles are angles that add up to 90°.

Let's say angle 1 is x, and angle 2 is 87.6 less than x.

We already know that angle 1 + angle 2 = 90, so we can just substitute x now.

We know that complementary angles add up to 90, so one of the angles is 90-x, and the other one is 90-x-87.6.

x = (90 - x) - 87.6

Simplifies to:

x = 2.4-x

Add x to both sides

2x = 2.4

Divide by 2

x = 1.2

To get the other angle, add 87.6 to 1.2

1.2+87.6 = 88.8

So, angle1 = 1.2, and angle2 = 88.8

Let's check our work.

88.8 + 1.2 = 90, so the angles are complementary and have a difference of 87.6

Hope this helps (:
