Question

Hello people ~

Answer 1

(b) 11°

The sum of two angles is equal to 90 degrees.

Here, one angle is 79°

• let the other angle be x

steps:

• x + 79° = 90°

• x = 90° - 79°

• x = 11°

Answer 2

Hey there!

Complementary angles add up to 90 degrees.

We are given

An angle of 79 degrees

and we're asked to find the complement of the angle.

So let's set up an equation:

79+x=90

where x=the unknown angle

Subtract 79 from both sides:

79-79+x=90-79

x=11

Hence, the measure of the unknown angle is

$\boxed{\boxed{\bold{11}}}$

Hope everything is clear.

Let me know if you have any questions!
