Answer: 63.27
Explanation:
In trigonometry , if we have a right triangle , then the ratio of the side opposite to an angle and the side adjacent to angle is the tangent of that angle.
From the given figure , we have a right triangle with
Side adjacent to the angle 49°=55 units
the sides opposite to angle = x
Then by trigonometry , we have

Hence, the value of x = 63.27
