We know that tan(θ) = opposite/adjacent. Let our angle θ (theta) = 29 degrees. The opposite side to our angle is x and the side adjacent to our angle is 10. Therefore, our formula is: tan(29) = x/10 Multiply both sides by 10 to solve for x and then we have: 10*tan(29) = x, which is equal to 5.5431... degrees So the answer is C.
