Answer:
12
Step-by-step 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
-7 and 5
You can get this by factoring to the following
(x + 7)(x - 5)
Then set both equal to zero and solve individually.
