<span>tan θ is defined as the opposite/adjacent side to the angle in a triangle
in this case you have a triangle which forms from (0,0) to (5,0) and (5,15), with </span><span>θ at (0,0)
-> your x coordinate is the adjacent side, and y the opposite
</span>
<span>tan θ=opposite/adjacent=y/x=15/5=3</span>
Note that one side is 20 ft, and the other is 16.
This means that the side that is part of the triangle is 4 ft.
The measurement is still the same for the triangle's height.
Find the area of the rectangle:
24 x 16 = 384
Find the area of the triangle:
4 x 24 = 96
Add the two numbers together:
384 + 96 = 480
You're answer is (C)
hope this helps
Answer: The answer is 25
Step-by-step explanation:
First, You would add the two numbers together, which you get 155
Then, the degrees of a triangle is equal to 180. So you would subtract 155 from 189, and you should get 55.
