ΔRST is a right triangle with m∠S = 90°. RS = 48, cos R =24/25 ; Find sin R. 

a. 7/24

b.25/24

c.7/25     <<<---===  sin(R) = sqrt%281-cos%5E2%28R%29%29 = sqrt%281-%2824%2F25%29%5E2%29 = sqrt%28%28625+-+576%29%2F625%29 = sqrt%2849%29%2F25 = 7%2F25.


The info RS = 48 is not relevant.

They put/include it with the only goal to confuse you.

RS CANNOT = 48. It's NOT THE HYPOTENUSE!

For the life of me, is it SO, SO DIFFICULT to state a problem correctly? 

How do you expect to get help if you at least CAN'T state a simple problem correctly?
