Answer:
324
Step-by-step explanation:
This is because when rounding you multiply 55 by 6 that is equal to 330 which is near 324. However if you want the answer spot on it would be 294
Answer: Tina rides 4 miles and Derek rides 3 miles.
Explanation:
Since we have given that
Distance covered by Derek in west direction be x
Distance covered by Tina in south direction be x+1
Distance between the bikers when they both stop is x+2
Since it forms right triangle, so we will apply "Pythagorus theorem":
Since distance can't be in negative sign, so we take x=3 miles
Derek rides 3 miles
Tina rides is given by
Hence, Tina rides 4 miles and Derek rides 3 miles.

Step-by-step explanation:
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.
