The angle of elevation to the top of a 15-story skyscraper is measured to be 4from a point on the ground 2,500 feet from the bui

alexandr1967 [171]

The point of observation is 2500 m away from the foot of the building.

The angle of elevation is 4°.

We need to find the height 'h' of the building.

With respect to 4°,

2500 is the adjacent side.

'h' is the opposite side.

The trigonometric ratio associating opposite & adjacent is tan.

We have

$tan\theta =\frac{opposite}{adjacent}$

$tan4^{o}=\frac{h}{2500}$

Cross multiplying we get

h = 2500 tan4°

h= 174.82 m

Option B) is the right answer.

The length of a rectangle is three times its width. The perimeter of the rectangle is at most 112cm. Which inequality models the

miss Akunina [59]

Answer: w ≤ 14 cm , L ≤ 42 cm

Step-by-step explanation:

width (w): w

Length(L): 3w

Perimeter (P) = 2w + 2L

P ≤ 112

2w + 2L ≤ 112

2(w) + 2(3w) ≤ 112

2w + 6w ≤ 112

8w ≤ 112

w ≤ 14

map of a city uses the scale 1 cm equals 50 m. On the map, South Street is 25 cm long. If there is a traffic cone at the start

aivan3 [116]

Answer:

125 traffic cones

Step-by-step explanation:

In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:

$\frac{centimeters}{meters}=\frac{1}{50}=\frac{25}{x}$ , where 'x' is the number of meters

cross-multiply: x = 25(50) or x = 1250 m

Since there is a cone every 10 m, we can divide the total number of meters by 10:

1250/10 = 125 cones
