Answer:
<h3>20.6 ft</h3>Step-by-step explanation:
You must use the trigonometric function.
In this case, it will be tangent.
We have
Substitute:
<em>multiply both sides by 20</em>
Tree height is r + 5.

Answer:
Figure 3: 28.5 units²
Figure 4: 33 units²
Figure 5: 25 units²
Figure 6: 30 units²
Figure 7: 25 units²
Figure 8: 32 units²
Reasons:
Figure 3 consists of<u> </u><u>2</u> shapes, A <u>rectangle </u>and a <u>square</u>
████████ ◣
rectangle: ████████ triangle: █◣
████████ ██◣
rectangle:
to calculate a <em><u>rectangle's </u></em>area: multiply the lengths of the width and height:
████████= width 8 █
█ =height 3
█
now substitute the values of W and H:
<u>rectangle area = </u><u>24</u>
Triangle:
to find the area of a <u><em>triangle</em></u>, multiply the width and height and divide by two:
◣ + ◣ = █ 0.5 + 0.5 = 1
█
███=width 3 █ =height 3
█
now substitute W and H
<u>Triangle area:</u><u> 4.5</u>
Now add the Rectangle Area To the triangle Area:
4.5 + 24 = 28.5
Final answer:
AREA =2 8.5
hope this helps!
