Hookes law states that the distance a spring is stretched is directly proportional to the force applied. if 20 pounds of force stretches a spring 4 inches , how much will the spring stretch if 80 pounds of force is applied ? ?

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.

do you have the measurements?
