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.

there are 2.54 centimeters in 1 inch. there are 100 centimeters in 1 meter.questionto the nearest meter, how many meters are in
Gre4nikov [31]

There are 7 meters in 279 inches.

  • There are 2.54 centimeters in 1 inch.
  • There are 100 centimeters in 1 meter.
  • The number of inches is given to be 279.
  • Unit conversion is a multi-step procedure that includes multiplying or dividing by a numerical factor, determining the appropriate number of significant digits, and rounding.
  • First of all, we need to convert inches to centimeters.
  • 1 inch equals 2.54 centimeters.
  • 279 inches equals 2.54*279 centimeters.
  • 279 inches equals 708.66 centimeters.
  • Now, we need to convert these centimeters into meters.
  • Meters in 100 centimeters = 1
  • Meters in 1 centimeters = 1/100
  • Meters in 708.66 centimeters = (1/100)*708.66
  • Meters in 708.66 centimeters = 7.0866
  • Thus, there are approximately 7 meters in 279 inches.
