Answer: height of the tower is 1064 feet
Step-by-step explanation:
We want to determine the height of the tower.
Assuming her line of sight of the top of the tower is a straight line, then a right angle triangle is formed. The height, h of the tower represents the opposite side of the triangle. Her distance from the foot of the tower represents the adjacent side of the triangle.
To determine h, we would apply the tangent trigonometric ratio which is expressed as
Tan θ = opposite side/adjacent side
Therefore,
Tan 85.7 = h/80
h = 80tan 85.7
h = 1064 feet
Answer:
40
Step-by-step explanation:
To find the area of a parallelogram, you use the following formula:
base x height = area
Using this formula, we plug in the values the question provides, and solve for the area:
base x height = area
8 x 5 = area
40 = area
Answer:
34, -102
