Question 341413: Hi,
I am currently tutoring H.S. Math and I'm horrible at Math! Do you have a good book (text book or otherwise) that you could recommend, when teaching H.S. Math?
Also, I'm stuck on this question....
At Southport College, walkways currently run between buidlings as follows: from Hammond to Fields, and from fields to Watson (as shown in the diagram below). However, students walking from Hammond to Watson routinely cut across the lawn.
And then there is a picture of a right triangle: the base is 20 m, the other side is 48 m and then the third side is the proposed walkway, which you have to figure out.
Haniya, who supervises maintence, plans to propose a direct walkway from Hammon to Watson. In her report, what length, in meters, should she indicate for the propsed walkway?
the answers are:
1) 50
2) 52
3) 56
4) 58
5) 68
The answer is 2) 52.
How do I do this problem? Step by Step....
Thank you!

You can put this solution on YOUR website! Your answer of 52 happens if the triangle is a right triangle and one of the legs of the right triangle is 20 and the other leg of the right triangle is 48.
Then you use the Pythagorean formula to get:
c^2 = a^2 + b^2, where c is the hypotenuse of the right triangle and a and b are legs of the right triangle.
The formula becomes c^2 = 20^2 + 48^2 = 400 + 2304 = 2704.
c becomes the square root of 2704 which equals 52.
It takes you through elementary algebra, intermediate, and college (advanced) algebra.
To tutor high school math, you need to know algebra, geometry, and trigonometry.
There are many sources.
A good online source for algebra that I have used can be accessed through the following link:
http://www.wtamu.edu/academic/anns/mps/math/mathlab/col_algebra/index.htm
A good refresher for trigonometry can be found at the following link.
http://www.clarku.edu/~djoyce/trig/
A decent refreshed for geometry can be found at the following link.
http://regentsprep.org/Regents/math/geometry/math-GEOMETRY.htm
For textbooks, I would recommend going to Amazon.com and looking for textbooks.
They have ratings that can help guide you to the right source.
There are many other tutorials online.
Just do a search on "geometry tutorial" or "trigonometry tutorial" or "algebra tutorial" and you will come up with a bunch.
Check them out and pick the ones that make the most sense to you.
You can also a search on "... lessons", or just "geometry" or "trigonometry" or "algebra".
You can experiment with the terms to narrow down your search results.
After a while you will get better at it, assuming you haven't done it before.
I believe algebra.com also has lessons, although I haven't used them very much.
To see the lessons that algebra.com has, use the following link.

You might even see some of my lessons in there.
Look for Santa.
