The height of a building is 58.08 meters if the angle is 71 degree and the distance between A and B is 20 meters.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
Angle = 71 degree
Distance between A and B = 20 meters
Let's suppose the height of the building is x meters.
From the right angle triangle applying the tan ratio:
tan71 = x/20
x = 58.08 meter
Thus, the height of a building is 58.08 meters if the angle is 71 degree and the distance between A and B is 20 meters.

First look at the Brackets
There are no indices in the brackets
There is no division in the brackets
There is a Multiplication in the brackets 7 x 3
For the answer
(9 - 7 x 3 + 4)²
Brackets
Multiplication 7 x 3 = 21
(9 - 21 + 4)²
Addition -21 + 4 = -17
(9 - 17)²
Subtraction 9 - 17 = -8
-8²
Now start again once the brackets are gone
-8²
Indices
-8 x -8 = 64
