Solution to Problem
The initial pattern for solving this type of problem is remembering the definition of Tangent of angle θ. For example the given opposite side is 200 ft, the angle in degree is 15 degree. Now you can calculate the adjacent side .

Tangent of °
| = |
opposite side
adjacent, Answer
|
Calculate the adjacent Side
Next you add the 746.41 + 250 to get your new adjacent side which is 996.40. The opposite side is 200 ft. Next you can calculate the angle in degree using the definition of tangent.

Arc Tan(θ) ° Answer
| = |
opposite side
adjacent side
|
Calculate the Angle in degree
Formula Recall:
Sine of angle θ = opposite side of angle θ divided by hypotenuse.
Cosine of angle θ = adjacent side of angle θ divided by hypotenuse
Tangent of angle θ = opposite side of angle θ divided by adjacent side
