Question 93123This question is from textbook
: Hello,
Problem:
The base of a triangle is 3cm greater than the height. The
area is 14 cm^2. Find the height and the length of the base.
I know that I have a consecutive number - (n+3) and I know I have
to apply a formula A= 1/2(b)(h) or is it the A=l(w). I tried it
using both, and still am not doing it right...I also know that I have
to do factoring in there, once I get my equation right. Than do
the whole take it zero thing. So I know the steps but not getting
them in order properly....Thanks so much!!!

Question 93150This question is from textbook
: Problem:
One leg of a right triangle has a length of 3m. The other sides have lengths that are consecutive integers. Find these lenths.
The other leg is ____ m
The length of the hypotenuses is ____m

I get the consecutive inegers n, n+1
and if I use the formula a^2 + b^2 = c^2 - I don't know what
to plug in for c. I've been shown several ways, and now
I'm just confused.

Question 93794: I have a square, divided up into 4 quadrants and need to know which quadrant a point lies in. I know the length of all 3 sides of the triangle (the edge of the square is 90', and the other two sides are lengths from 2 adjacent corners to the point, e.g. 48' and 63'). How do I best figure the angles of the triangle in order to calculate where the point lies, or is there another way to do this?

Question 95181This question is from textbook Precalculus Mathematics for Calculus
: Hello, I managed to find the solution to this question through trial and error, but I am very curious to see how it is properly solved.

This is from my Precalculus book published by brooks/cole. (Precalculus Mathematics for Calculus Fifth Edition by Stewart Redlin and Watson)

" 78. Dimensions of a Lot
A city lot has the shape of a right triangle whose hypotenuse is 7 ft longer than one of the other sides. The perimeter of the lot is 392 ft. How long is each side of the lot? "

After hours of attempts and searching for clues I found a web site that let me plot the two sides and gave me the length of the hypotenuse. I finally came up with this: one side 49 ft, the other side 168 ft, and the hypotenuse 175 ft. 175+168+49=392 175-168=7

Thanks in advance
