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.

Answer:
Ok for your question 1+1. In my calculations, that is 2.
I hoped this helped have a good day :)
There is 1000 milliliters in a liter. So we're gonna work with thirds. One third is already filled, so that means two thirds is not . So 4 liters fills up 2/3 which we can infer that 2 liters fills up one third of the area... so there is 6 liters in total. Which means there is a total of 6000 milliliters of paint.
Yes, since 50 x 10 = 500.
