You are flying a kite at an angle of 70 degrees. you have let out a total of 400ft of string and are holding the reel steady 4 feet above the ground. a friend watching the kite estimates that the angle of elevation to the kite is 85 degrees. how far from your friend are you standing?

170.466 feet

Step-by-step explanation:

Given that the kite had an angle of elevation of 70 degrees and 4 ft above the ground.

Using sine values, we find that the height of the kite above the reel would be

Total height from the earth = 379.88+4 = 383.88 ft.

The friend estimates the angle of elevations as 85 degrees

i.e. if d is the distance from the kite position, then we have

d=383.88 cot 85

=33.586 ft

Distance of you from the kite

Distnce between friend and you = 136.88+33.586

= 170.466 feet

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
