Answer:
x= 35° hope this helps!!!
Answer: 35°
Step-by-step explanation: the total of a triangle's angles always equals 180° and we know 2 of the angles so if you add the two (55+90=145) and subtract that from 180 (145-180=35) you get 35°
A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50° angle
of elevation. His eyes are 5 feet above the ground. Using cos 50° 0.64, what is the height of the tree
to the nearest foot?
36 feet
29 feet
24 feet
31 feet
Answer:
[tex] \tan(50) =opp(x) \div adh(20) \\ \tan50 \times 20 = opp(h) \\ = 23.8 [/tex]
therefore the answer is 24
The height of the tree is approximately 26 feet.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Let's denote the height of the tree with 'h'.
Then we can use the trigonometric ratio for cosine as follows:
cos(50°) = adjacent/hypotenuse
cos(50°) = 20/h + 5 (the adjacent side is the distance from the student's eyes to the tree, which is 20 feet, and the hypotenuse is the height of the tree plus the height of the student's eyes, which is h + 5 feet)
Now we can solve for 'h':
0.64 = 20/(h + 5)
0.64(h + 5) = 20
0.64h + 3.2 = 20
0.64h = 16.8
h = 26.25
So the height of the tree is approximately 26 feet (rounded to the nearest foot), which means the closest answer choice is 29 feet.
Therefore,
The height of the tree is approximately 26 feet.

Explain how to find the volume of the prism below. Be as specific as possible, using the formula: V= Bh.
Answer:
v= area of triangle * height
Step-by-step explanation:
Answer:
V = AREA OF BASE * HEIGHT
Step-by-step explanation:
V= [tex]\frac{AB}{2}[/tex] × H
V= [tex]\frac{12*9}{2}[/tex] × H
V= [tex]\frac{108}{2}[/tex]× 18
V = 54 * 18

1. Is the graph proportional?
2. How many feet can a sloth travel in 20 minutes?
Answer:
1. Yes
2. 60
Step-by-step explanation:
The graph is proportional because it passes an origin point.
The equation of the graph is
[tex]y = 3x \: \: (x \geqslant 0) \: \: (y \geqslant 0)[/tex]
We can find the distance when travelling in 20 minutes by substituting x = 20 in the equation.
[tex]y = 3(20) \\ y = 60[/tex]
Therefore the distance (ft) is 60.
ASAP Please answer. Three students sit in the first row. In the second row, 3 students sit behind each of those students, and so on. Write an expression with exponents to show how many students sit in the third row? How many total students are seated?
Answer:
3^2, 9 students.
Step-by-step explanation:
I'm not 100 percent sure about this but I'm pretty sure that because there are 3 rows you can just do 3^2 which is 9.
Answer:
3^x. 39
Step-by-step explanation:
To find the expression, we know the first row is 3 and the next row is 9. So the pattern is multiply by 3. That means the expression is 3^x. Following that, we know the third row is 27. 3 + 9 + 27 = 39

Traverion wants to find the answer to the question “How much money does the average college professor make?” He surveys 50 professors from the university in his hometown. Which best describes whether or not the results of his survey would represent the responses from the entire population of college professors?
The results do not represent the population because not all college professors actually responded.
The results do not represent the population because the sample does not represent professors from different areas.
The results represent the population because the sample contained college professors and the population is college professors.
The results represent the population because he sampled a large number of professors.
Answer: I'm pretty sure it's the second option, The results do not represent the population because the sample does not represent professors from different areas.
Step-by-step explanation: It wants the average pay of professors everywhere,not the average of that specific college. I hope this helps sorry if I'm wrong :)
