Answer 1

77.7

Explanation:

if you know, you know. laso make sure your calculator is on degrees and not radians

Answer 2

The calculated height of the building is 77.7 feet

How to determine the height of the building

from the question, we have the following parameters that can be used in our computation:

The building

The height of the building h can be calculated using the following sine ratio

sin(51) = opposite/hypotenuse

Substitute the known values into the equation

sin(51) = h/100

So, we have

h = 100 * sin(51)

Evaluate

h = 77.7

Hence, the height of the building is 77.7 feet
