Todd's friend Olivia is flying her stunt plane at an elevation of 6.3 km. From the ground, Todd sees the plane moving directly t
topjm [15]
 So the plane of Olivia travels from west to east with an elevation of 6.3 km. To summarize everything and to get the speed of the plane, I used the Angle Side Angle Triangle Theorem and also the law of sine and the formula would be the following:

First is to get the distance traveled by the plane within the range of 3 minutes. To get that distance you must get the following variable. 

total distance = distance travel from west to Todds position + distance traveled from Todds position to the reach of the elevation

Dt = D1 + D2 

first is getting the D1

D1 = sin41 (6.3) / sin 49
(by following the law of sine and the angles is based on the triangle)
D1 = 5.477 km 

then get D2,
D2 = 6.3 sin 65 / sin 25
D2 = 13.510 

After that get the total distance 

Dt = D1 + D2
Dt = 18.987 km 

To get the speed of the plane, you must divide the distance to the time (in minutes) then multiply it by 60 to make it as an hour.

Speed = 18.987 /3 * 60 = 379.74 km/hr

you are standing at point b. point b is 16 feet from the center of the circular water storage tank and 15 feet from point A. AB
Jobisdone [24]
The points A and B and the center O  of the circle form a right angle and AO = radius.
So by Pythagoras
16^2 = 15^2 + AO^2

AO = sqrt (16^2 - 15^2)

AO ( radius) =  sqrt31 =  5,57 feet  answer (to nearest hundredth)
