We can use Trig to solve this problem. The trig function Tangent will help us.
Tangent=opposite/adjacent
Therefore:
Tan(41°)=12/x.
(12)Tan (41°)=x because we multiplied 12 on both sides to isolate X.
X=10.43 because we plugged the above statement into the calculator.
The answer: X=10.4 by rounding.
