sin^-1(5/10) = sin^-1(1/2)  = 30 degrees or 150 degrees if the angle is in the 2nd quadrant

It depends upon whether side 'c" is a leg or the hypoteneuse

If its the hypoteneuse, then angle A = 90 - 28 = 62

And we have

sin(62) = A / 54.8     multiply both sides by 54.8

54.8 sin (62) = A = about 48.39 in.

If c is a leg, then A has to be the hypoteneuse (or else angle B would = 90)

So....angle C = 62 degrees   and we have

sin (62) = 54.8 / A       rearranging, we have

A = 54.8 / sin(62)  = about 62.06 in.

I'm not totally sure about this, but I believe the net price factor is found thusly...

[100-18] / 100 * [ 100 - 15] / 100 * [100 - 5]/ 100 =

.82 * .85 * .95 = 0.66215

And applying this factor to the price, we have the net price =

$425.80 * 0.66215 = $281.94

We can use the sine to solve this....the "opp" is the height off the ground......

sin (35) = opp / 15    multiply both sides by 15

15 sin(35) =  about 8.6 ft

(m^2)(n^2)-(m^3)n)/(mn)   the greatest common factor in the numerator is m^2n...so we have

[m^2n] [ n - m] / [mn]  =

m [ n - m ] =

mn - m^2

I don't understand what is being asked, here (???)

Thanks for that correction, JonesDaBoi...I think DaMaster just made a small "sign" error....

I assume you're talking about square roots (root 2) and cube roots (root 3). A square root indicates that there is some number multiplied by itself once that will give the number under the square root. A cube root indicates that there is some number multiplied by itself twice that will give the number under the cube root.
