This requires calculator as it is not a common angle such as 60degrees or 30degrees
there is only one approach to this problem with the #s given
Sin(insert degree)= opposite/hypotenuse
Cosine (insert degree) = adjacent/hypotenuse
Tangent (insert degree) = opposite/ adjacent
In this case, the only usable angle is the 65 degree since the opposite of the right angle is the hypotenuse which is not given.
With the 65 degree, one can only use tangent as the hypotenuse is not given
Tan 65 degrees = x/7
7(tan 65 degrees) = x
15.01 = x
