Answer:
34.9 units
Explanation:
This problem involves the use of trigonometric ratios. This problem specifically uses the tangent ratio as it provides the leg adjacent to the angle and asks us to find the opposite leg.
tan(64°)=x/17
tan(64°)*17=x/17*17
tan(64°)*17=x
tan(64°)*17=x
x=34.855
The length of the leg is 34.9 units
