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

Answer:
9 & 2.
Step-by-step explanation:
let x represent the unknown numbers.
x + x-7 = 11
2x = 11+7
2x = 18.
divide both sides by 2.
x = 9.
x-7 = 9-7 = 2
2 ( x + 1 ) = 12
Use distributive property:
2x + 2 = 12
Subtract 2 from both sides:
2x = 10
Divide both sides by 2:
X = 5
First, you are going to distribute the 3 into the (6x+2x) and the 8 into the (5x+6). After that, the parenthesis should be gone. Then, move all the x values to one side, and the constants to the other. Then, solve as you normally would.
