Question

Find the value of x.

Answer 1

8

Explanation:

(6x + 2) + 40 = 90 because the entire angle is a right angle, therefore the whole angle is 90

subtract 40 from each side: 6x + 2 = 50

now subtract 2 from each side: 6x = 48

now divide 6 from each side: x = 8

Answer 2

x=8

Explanation:

Set 40 + y = 90

y=50

y = 6x + 2

6x + 2 = 50

6x = 48

48/6 = x

x=8
