The height of the skyscraper if the angle of elevation to the top of a prominent skyscraper to be 17° is 91.51 meter
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the skyscraper, hence:
tan(17) = h/294
h = 89.88 meter
Total height = 89.88 + 1.63 = 91.51 meter
The height of the skyscraper if the angle of elevation to the top of a prominent skyscraper to be 17° is 91.51 meter
