Answer:
The answer is : 23.25 in ²
Step-by-step explanation:
There are 3 triangles with the same lengths: height = 5in and base = 5 in
There is one triangle: height = 4.3 in base = 5 in
Formula
Area = height x base / 2
For the triangles
Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²
For the triangle
Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²
Total surface area = 12.5 + 10.75 = 23.25 in²
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.

Step-by-step explanation:
slope, m = (6-0) /(0--2) = 6/2 = 3
intercept, c at y = -2 when x = 0
Equation
y = mx + c
y = 3x -2
