3j - 2 - 5j - 4
<em><u>-2j - 6</u></em>
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.

Answer:
a
Step-by-step explanation:
(√12 + 6)(-√8 -√2) = (√3×4 + 6)( -√2×4 -√2) =
(2√3 + 6)( -2√2 - √2) = (2√3 + 6)(-3√2) = -6√6 - 18√2
Answer:
2/3
Step-by-step explanation:
written in the standard form of Ax + By = C, so its slope is equal to –A/B, or –2/–3, which equals 2/3.
