The way u can get ur answer is multiply 17 time 5 then u will get your answer
Just measure the width (or height, if you'll be stacking the pennies
a mile high) of a penny, then divide 5280 feet by whatever you find.
This is a great activity for a class, and in fact a good way to start
the project. First take one penny, and work out an answer. Then get
100 pennies, and measure them; do the same calculation to see how many
pennies it will take to make a mile. There will probably be a
difference, because you can measure 100 pennies more accurately than a
single penny. Or maybe you have a micrometer that will measure one
penny precisely. Which is better can be a good discussion starter. And
don't forget to try it in metric, too.
Just to illustrate, using a very rough estimate of a penny's width,
let's say a penny is about 3/4 inch wide. The number of pennies in a
mile will be
5280 ft 12 in 1 penny
1 mile * ------- * ----- * ------- = 5280 * 12 * 4/3 pennies
1 mi 1 ft 3/4 in
This gives about 84,480 pennies. (This method of doing calculations
with units is very helpful, and would be worth teaching.)
If we measure 100 pennies as 6 ft 1 in, we will get
5280 ft 100 pennies
1 mile * ------- * ----------- = 5280 * 100 * 12 / 73 pennies
1 mi 6 1/12 ft
This gives us 86794.5205 pennies in a mile.
You have to use Pythagoreans theorem. 225=144+x^2
x^2 = 81
sq root of 81 is 9
it is 9 feet away from the wall.

The objective is to determine PR
From the diagram we see that MQ is a straight which implies that the the angle
Now looking at triangle NMP we see that
![\theta _{MNP} = 180 -[ \theta_{NMP} + \theta _{NPM}]](https://tex.z-dn.net/?f=%5Ctheta%20_%7BMNP%7D%20%3D%20%20180%20%20-%5B%20%5Ctheta_%7BNMP%7D%20%2B%20%5Ctheta%20_%7BNPM%7D%5D)
![\theta _{MNP} = 180 - [60 + 78 ]](https://tex.z-dn.net/?f=%5Ctheta%20_%7BMNP%7D%20%3D%20%20180%20%20-%20%5B60%20%2B%2078%20%5D)
Now the measure of an inscribed angle is half the measure of its arc intercepted, this statement is the inscribed angle theorem
So with the knowledge
Then
Looking at the diagram we see that
