A flagpole that is 21 ft tall casts a shadow that is 30 ft long. What is the angle of elevation of the sun when this shadow is cast?
Answers
Answer:
34.99°
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE
Let angle( X) = angle if elevation
From trigonometry, tan(X)= opposite/ adjacent
Height of the flagpole= 21 ft , which is the opposite side
The base, adjacent side = 30 ft
If we substitute the values we have
Tan(X) = 21/30
Tan(X)= 0.7
Tan-1(0.7)=34.99°
Hence, the angle of elevation of the sun when this shadow will cast is 34.99°

A parabola has focus (5,1) and directrix y=-3.
Where is the parabola’s vertex?
Answers
Answer:
vertex = (5, - 1 )
Step-by-step explanation:
The focus and directrix are equidistant from the vertex
Since the equation of directrix is y = - 3 then the parabola is vertical,
The distance between the focus and directrix is
| 1 - (- 3) | = | 4 | = 2
Thus the vertex is 2 units below the focus
vertex = (5, 1 - 2 ) = (5, - 1 )
A parabola has focus (5, 1) then the vertex of the parabola will be (5, -1).
What is a Parabola?A location on the curve that is equally spaced from both a fixed location and a fixed line is referred to as a parabola. The parabola's focus requires and fixed line are referred to as its foci and directrix, respectively.
As per the given information in the question,
The focus and directrix are equidistant from the vertex then,
The parabola is vertical because the directrix's equation is y = - 3; hence, the focus and directrix are separated by:
|1 - (-3)| = |4| = 2
The vertex is therefore 2 units below the focus.
vertex = (5, 1 - 2) = (5, -1)

A triangle prism has a volume of 240m3.The area of the base is 16m2 what's is the height of the triangle prism
Answers
Answer:
The height is 45 m
Step-by-step explanation:
The volume of a triangular prism is V = (1/3)(area of base)(height)
If the voume is 240 m^3 and the area of the base 16 m^2, then the height of the prism is determined as follows:
3V = (area of base)(height)
Dividing both sides by (area of the base), we get:
3(240m^3)
height = ------------------------- = 45 m
16 m^2
