I used tan but there's probably an easier way to do this but 4*tan(20)=8.94 then round it up to 9
10
because 25 is 5 times as much so you multiply 5 by 2 and you get 10.
Add 8 to both sides
12x = 40 + 8
Simplify 40 + 8 to 48
12x = 48
Divide both sides by 12
x = 48/12
Simplify 48/12 to 4
<em>x = 4</em>
<u>Answer: A. 4</u>
x>3
