2 times negative 3 equals negative 6
6x + 2x - 1 = 5x + 11
8x - 1 = 5x + 11
- 5x - 5x
3x - 1 = 11
+ 1 + 1
3x = 12
3 3
x = 4

<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.
