Question

Find the value of x

Answer 1

x=12

Explanation:

Since the two angles are complementary, both angles add up to 90°.

So, to find the value of the other angle, simply subtract 35 from 90.

90-35=55

Now we know that the expression is equal to 55.

4x+7=55

Subtract 7 from both sides.

4x=48

Divide both sides by 4.

x = 12

Answer 2

x=12

(90-35)-7/4
