Question

(2c+8) °
and
(6c-6) °
What is “ c “

Answer 1

`\huge \mathfrak {equation}`

`(2c + 8) + (6c - 6) = 90`

This is because these two angles form a right angle

Combine like terms

`8c + 2 = 90`

Subtract two from both sides

`8c = 88`

Divide both sides by 8

`c = 11`

Answer 2

c = 11

Explanation:

The two angles form a right angle, indicated by the square at the corner of the angle. Right angles have a measure of 90 degrees.

This means that 2c + 8 + 6c - 6 must equal 90

2c + 8 + 6c - 6 = 90 solve for c

combine like terms

8c + 2 = 90

subtract 2 from both sides

8c = 88

divide both sides by 8

c = 11
