Answer:
16
Step-by-step explanation:
When the hypotenuse is given, you can use this formula to solve for the leg
b = root c^2 - a^2
b = root 20^2 - 12^2
b = 16 in
Hope this helps!
To solve, you need to carry the decimal two spaces to the right because there are two zero in 100 so 0.17 times 100 is 17. The height of the tree after ten years was 17 meters tall in height.
A regular dodecagon is a polygon with 12 equal sides.
Length of each side = 108/12 = 9 cm.
Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm
Area of each triangle = 9/2(16.79) = 75.57 cm^2
Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2
