Given both the distance from the tree and the height of the tree, the angle of elevation can be obtained using the tangent formula, tangent theta = opposite side / adjacent side. In this case, opposite side = the tree's height and the adjacent side is the distance of Cisco to the tree. Therefore, the angle of elevation equals 40.03 degrees.
One fifth is 20% or0.2 so times 4 because you have four 20%
Area of base of Triangle
= ½(15)(5)
= 37½ units²
Area of sides of Triangles
= (15 × 9) + ½(17)(15)
= 262½ units²
Total surface area of Triangle
= 262½ + 37½
= 300 units²
