<u>Given:</u>
The angle of elevation from the point on the ground to the top of the tree is 34° and the point is 25 feet from the base of the tree.
We need to determine the height of the tree.
<u>Height of the tree:</u>
Let the height of the tree be h.
The height of the tree can be determined using the trigonometric ratio.
Thus, we have;
Substituting the values, we get;
Multiplying both sides by 25, we have;
Rounding off to the nearest tenth of a foot, we get;
Thus, the height of the tree is 16.9 feet.
Hence, Option B is the correct answer.
Answer:
Step-by-step explanation:
GIVEN: A bicycle training wheel has a radius of . The bicycle wheel has a radius of
.
TO FIND: Approximately how much smaller, in square inches, is the area of the training wheel than the area of the regular wheel.
SOLUTION:
radius of bicycle wheel
area of bicycle wheel
putting value,
area of bicycle wheel
radius of bicycle training wheel
area of bicycle training wheel
putting value,
area of bicycle wheel
difference in area of bicycle wheel and bicycle training wheel
hence the training wheel is smaller than regular wheel
