Question

Solve for x in the diagram below. Numerical answer only, no units

Answer 1

12

Explanation:

Since it is on a right angle we can equation the sum of both angles to 90:
6x-2+20 = 90

Now we simplify:

6x+18=90

Now we subtract 18 from both sides:

6x+18-18=90-18

Simplify:

6x=72

Now we divide both sides by 6:

6x÷6=72÷6

Simplify:

x = 12
