What are the values of a and b in the equation A a = 2, b=4
B a = -2, b=4
C a=-2, b= -4
D a=2, b= -4

a= -2     b =4

Step-by-step explanation:

I put it in a calculator and found the answer

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
