Answer:
Step-by-step explanation:
We need to note that this is an equation, in which we can solve for x.
We can use a calculator to find the tangent of 39 - we type 39 into the calculator then press the "TAN" button to find it's tangent. We find that to be around 0.81.
We now have the formula simplified down to . To solve for x, we want to isolate it on one side, so we can multiply both sides by 68 to get rid of the fraction.
We know have
, so x is approximately 55.
Hope this helped!
