What is the result of subtracting the second equation from the first? \begin{aligned} 8x-4y &= -4 -3x+4y &= 5 \end{aligned}
8x−4y=-4
−3x+4y=5

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.
