2. janice is buying paint to paint her new apartment. the store sells paint in one-gallon cans. how accurate does her estimate need to be for the amount of paint needed?
3. a city planner is measuring the distance of one city block. which unit of measure should she use: 1 mile, 1 meter, inch?

2.Janice should know the area of her apartment that  requires painting. This should be followed by calculating the area  that 1 gallon of the paint can completely  paint.Dividing the total area of the apartment to be painted with the area painted by a single gallon can will determined the number of gallon cans to buy for the apartment painting.

3. The approximate distance covered by 20 blocks is 1 mile.This is an example of Manhattan.A city planner can use this estimate to know the distance of a single city block by dividing 1 mile with 20 blocks.She can use 1 mile.

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).

one set of data has more variation than the other. hope this !
