Answer:
34.0 degrees, 29.6 feet in Diameter.
This is a right triangle trigonometry question.
Use half of the diameter to form the base of the triangle (19.3 ft) with a height 0f 13.
Use Inverse Tangent function to find the angle of repose
round to 34.0
then use the angle of repose to solve trigonometric function of the tangent for the radius of the other cone.
switch denominator and tangent
multiply by 2 to get diameter of second cone
14.82*2≈29.6
hopefully this helps!

Answer:
Step-by-step explanation:
d = r * t
Let the rate of the boat in still water = x
Let the rate of the stream = y
Against the current
24 = (x - y)* 4 Divide both sides by 4
24/4 = x - y
6 = x - y
With the current
24 = (x + y )* 3 Divide both sides by 3
24/3 = (x + y)
8 = x + y
Put the two equations together
x - y = 6
<u>x + y = 8</u> Add
2x = 14 Divide by 2
2x/2 = 14/2
x = 7
x + y = 8
7 + y = 8
y = 8 - 7
y = 1
The boat is going 7 miles per hour
The stream is going 1 mile per hour.
