A man is flying in a hot-air balloon in a straight line while keeping it at a constant altitude. As he approaches a parking lot

and notices that the angle of depression from his balloon to a friend's car is 36º. He flew directly over the car. A minute and a half later he had travelled 360 feet horizontally; he looks back to see his friend getting into the car and observes the angle of depression to be 37º. At that time, what is the distance between him and his friend?

Answer:

221°

Step-by-step explanation:

Using sine rule

a/sinA = b/sinB = c/sinC

A= 36°

B= 37°

C = 107°

It takes 90 seconds to go from point A to point B. To find a, we will use

a/sinA = c/sinC

a/sin36°= 360/sin 107°

a(sin 107°) = 360sin36°

a = 360sin 36° / sin 107°

a = 360(0.5878) / 0.9563

a = 211.608/0.9563

a = 221.27°

a = 221°

How do u do this problem
atroni [7]
Alexis and 3 friends buy:
-Pretzel $4.
-Sauce $1
-Drink $2

First we would multiply all the food prices by 4, since there is 4 people in total.
4 x 4 = $16
1 x 4 = $4
2 x 4 = $8

Now we're adding all the prices together. 
16 + 4 + 8 = $28

At this point, we're going to make the expression, using all the steps that we did.
( 4 x 4 ) + ( 1 x 4 ) + ( 2 x 4 )

We used parenthesis to show that those expressions need to be done first before anything else.

This is how we make an expression and we find the total answer.

The expression would be: ( 4 x 4 ) + ( 1 x 4 ) + ( 2 x 4 )
The total cost would be: $28

Hope this helps!~

If it takes 1/2 day to write a report, how much will be completed after 1/4 of a day?
lana [24]

Answer:

You have completed only half in a 1/4 of a day

Step-by-step explanation:

think of it this way

lets say in half a day e.g at 12pm you finish the report

half of 12 is 6

so that would be a 1/4 of the day

100%=24 hours=whole day

50%=12 hours=half a day

25%=6 hours = quarter of a day

25% = 1/4

i hope this helps
