Here we have two right triangles. And in such case we have to use altitude rule which is
ratio of part of hypotenue and altitude= ratio of altitude and remaining part of hypotenuse
So we get
r/h =h/s
So the correct option is s .
The distance of the ball from the foot of the tower is : 35.18m
The ball would be moved 57.2m away from the foot of the tower for the Angle of elevation to be halved.
<h3>What is angle of elevation?</h3>
Angle of elevation is the angle formed between the horizontal and the line of view from the vertical.
Analysis:
The height of the tower and the distance of the ball from the foot of the tower form a right angle triangle.
so we use trigonometry.
a) let distance of the ball from foot of tower be x.
so that, tan 52 = 45/x
x = 45/tan52
x = 45/1.279 = 35.18m
b) let the distance of the ball in the new position from the foot of the tower be y.
if the angle of elevation is halved, then new angle is 52/2 = 26°
tan 26 = 45/y
y = 45/tan26 = 45/0.487 = 92.4m
distance moved from old position to new position = 92.4 - 35.18 = 57.2m
In conclusion, the distance of the ball from the foot of the tower and the distance the ball should move to make its elevation 26° are 35.18m and 57.2m respectively.

A. true, P does two complete rotations returning to it's original spot. 720° / 360° = 2
B. false, reflecting across a line will move P.
C. true, moving up 2 then down 2 returns P to it's original position.
D. true, if P is on the line of reflection it remains there.
E. false, P does only 4.5 rotations moving to different coordinates. 1620° / 360° = 4.5
could you just show me the picture more better then mayebi can help you
