Finf the exact value of sin A and cos A where a = 9 and b = 10 and <c is a right angle
Katyanochek1 [597]
To solve for the longest side, the hypotenuse, you have to use the pythagorean theorem. It will be 10^2 + 9^2 = c^2. 100 + 81 =c^2. 
c^2 = 181 so c = sqrt(181).
to find sin of A do opposite/hypotenuse which gives you 9/sqrt(181)
to find cos of A do adjacent/hypotenuse which gives you 10/sqrt(181)

A store has 40% off sale on headphones. With this discount, the price of one pair of headphones is $36.00
Nataliya [291]

40 % off means we pay 60 %  (must total 100%)

original price * 60 % = 36.00

change percent to decimal

original price * .6 = 36

divide each side by .6

orginal price = 60
