PLEASE HELP I DON'T KNOW

65 people

Step-by-step explanation:

Imagine the situation backwards

Let's say the people who were originally on the train are all wearing red. You end with 63 people. Of these 63 people, 17 of them JUST got on and are wearing blue. So 63 people - 17 blue people is 46 red people (remember, we are trying to find all the RED people). Before all of this happened, 19 people had gotten OFF the train, and these people were part of the original group so they were also red. So now add the 46 red people on the train to the 19 red people that got off and you get 65

step-by-step explanation:

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).
