Answer 2

I will be right back with you, I promise! I'm here! Just need a sec!

Answer 3

ok(:

Answer 4

Ok, let me take a look.

Answer 5

Ok, wow you have several different things going at one time here. It looks like you have two congruent triangles with two other odd shaped things. Let's look at it and find the area of the two triangles first.

Answer 6

ok

Answer 7

ok so would I do 500 * 2.21?

Answer 8

No, that 2.21 is the angle measure there in radians. I a m figuring out the angle in degrees. Ok?

Answer 9

ok(:

Answer 10

Do you know the trig functions as they are defined in SOHCAHTOA? Or better yet, do you know the Law of Sines?

Answer 11

I do knoiw SOHCAHTOA, but I do not know the law of sines

Answer 12

Forget the Law of Sines; it won't work here. Sorry. Do you know how to find the measure of an angle when you know the side opposite it and the hypotenuse?

Answer 13

no I do not

Answer 14

Can you find the sin of angle A with what I have drawn for you? That triangle on the right is half of the other triangle. We can use that to find the measure of the angles in the pool and then use that info to convert the radian measure to degrees. It will be easier in degrees. Trust me. Can you find the sin(A)?
