Solve for x.A. x = 12B. x = 72C. x=64D. x=18

Q:
Solve for x.A. x = 12B. x = 72C. x=64D. x=18
Accepted Solution
A:
Hi there! The answer is A. x = 12
The angles (taken together) are complementary angles: the sum of the angles is 90 degrees. When we know this, we can set up and solve an equation.
(3x + 6) + 48 = 90
Work out the parenthesis
3x + 6 + 48 = 90
Collect terms
3x + 54 = 90
Subtract 54
3x = 36
Divide by 3
x = 36 / 3 = 12
Therefore, the solution for x, gives x = 12. A is the correct answer.
