If a rubber band is stretched a particular distance, the restoring force is defined as the force needed to
restore the rubber band to its original form. When a
particular rubber band is stretched to a length of 30
centimeters, the restoring force is –35 newtons, and
when it is stretched to a length of 90 centimeters, the
restoring force is –125 newtons. For every additional
20 centimeters from its original form, the restoring
force decreases by c newtons, where c is a constant.
What is the value of c ?

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
