You are standing 25 feet from the base of a flagpole.The angle of elevation to the top of the flagpole is 40°.What is the height

liraira [26]

Answer: the height of the flagpole is 21 ft

Step-by-step explanation:

Since the angle of elevation to the top of the flagpole is 40°, a right angle triangle is formed. The height of the flagpole represents the opposite side of the right angle triangle. Your distance from the base of the flagpole represents the adjacent side of the right angle triangle. Therefore, to determine the height of the flagpole, x ,we would apply the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side

Tan 40 = x/25

x = 25tan40 = 25 × 0.8391

x = 20.98

x = 21.0 ft to the nearest tenth.

In Seattle, the tax on a property assessed at $570,000 is $12,540. If tax rates are proportional in this city, how much would th

marta [7]

12,540 / 570,000 = x / 460,000
cross multiply
570,000x = 5768400000
x = 5768400000 / 570,000
x = 10,120 <=== tax on 460,000

Here's another Math one worth 10.

tia_tia [17]

<span>In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The short leg is </span>the side opposite the 30 degree angle. If the short leg =x, then the hypotenuse = 2x

The ratio of the short leg to the hypotenuse in the given triangle is cos(60°)

$
cos(60^o) = \frac{adjacent \ side}{hypotenuse } = \frac{x}{2x} = \frac{1}{2}$

Answer is C. 1:2
