The formula in computing the area of the triangle is:
A = bh/2
Where A = area of the triangle
b = base
of the triangle
h =
height of the triangle
What is asked in the problem is the height of the triangle
and you are already given the area so you substitute the given measurements to
the formula:
64 = 8(h) / 2
2 (64) = 8h
8h = 128
h = 16
Therefore, the height of the signal flag is 16 in
Answer:
Step-by-step explanation:
Answer: The tree was 27 feet tall
Step-by-step Explanation: First of all Sally was standing 30 feet away from the tree and she looks up at an angle of elevation of 38 degrees to the top of the tree. With this bit of information we can determine that a right angled triangle has been formed with the reference angle as 38 degrees, the side facing it as h (the height of the tree) and the adjacent side as 30. We shall apply the trigonometric ratio as follows;
Tan 38 = opposite/adjacent
Tan 38 = h/30
0.7813 = h/30
0.7813 x 30 = h
23.4 = h
We remember at this point that Sally’s eyes were 4 feet above the ground. What we have just calculated is the height of the tree from “4 feet above the ground” (where her eyes were). Hence the actual height of the tree is calculated as 23.4 plus 4 which gives us 27.4
Therefore the tree was 27 feet tall (approximately to the nearest foot)
