The diagram shows a 6 ft student standing near a tree. The shadow of the student and the shadow of the tree ends at point A. What is the height of the tree?
Answer: 18ft
Step-by-step explanation: I took the quiz and got 100%
The height of the tree is 8.3 ft.
To solve this problem, we have to find the angle of elevation from the student.
To do this, we have to assume or bring out a right angle triangle and solve for the.
Given that we have the distance of A to F and the point to F
A to F = 5ftE to F = 6angle ?Trigonometric RatioUsing trigonometric ratio,
We can find the tangent of this angle
[tex]tan\theta = \frac{opposite}{adjacent} \\tan\theta = \frac{6}{5}\\ tan \theta = 1.2\\\theta = tan^-^1(1.2)\\\theta = 50.2^0[/tex]
The angle of elevation can be calculated using sum of angles in a triangle is equal to 180 degrees
[tex]180 = 90 + 50.2 + x\\x = 180- 140.2\\x = 39.8^0[/tex]
Assuming a right angle triangle from the point the student is standing, the distance from him to the tree would be
[tex]15 - 5 = 10ft[/tex]
Let's use the tangent of the angle to find the height of the tree.
[tex]tan\theta = \frac{opposite}{adjacent} \\tan 39.8 = \frac{x}{10}\\x = 10 tan39.8\\x = 8.3ft[/tex]
From the calculations above, the height of the tree is 8.3 ft.

Question 4 A triangle has two sides that are 8 cm and 13 cm. What could be the length of the triangle's third side? Select three that apply. А 5 cm B 10 cm С 17 cm D 20 cm E 21 cm F 24 cm
know what is the third side length
the difference between the 2 other sides < the greatest side of triangle < the sum of 2 other sides
so here the answers here could be ( 10- 17 - 20)
10-8 < 13 < 10+8
13-8 < 17 < 13+8
13-8 < 20 < 13+8

what is the probability of rolling a 3
Answer:
1/6
Step-by-step explanation:
Answer:
1/6 if rolled on a dice.
Step-by-step explanation:
There are 6 options on a dice, so 6 is the denominator.
There is only one chance to roll a 3, so 1 is the denominator.
Therefore, the answer would be 1/6.

Tom has three times as many action figures as Jerry. If Tom has 27 action figures, how many does Jerry have? Write an equation that represents the scenario. Then solve.
Answer:
Jerry has 9 action figures.
Step-by-step explanation:
Since Tom has three times as many action figures as Jerry, Tom has 3x action figures, where x is the number of action figures that Jerry has.
Since Tom has 27 action figures, we can say that 3x=27.
3x=27
x=9

Write an
explicit formula for
an,
then
th
term of the sequence 100, 20, 4, ....
Answer:
Step-by-step explanation:
a1 = 100
r = 1/5
an = 100 (1/5)^(n - 1)
Try it. We have the answer for a_3
a_3 = 100 * (1/5)^(3 - 1)
a_3 = 100 * (1/5)^2
a_3 = 100 * 1/25
a_3 = 4 which is just what the series says should be the answer.
