One side of my triangle is 10' 2". The second side is 15' 3". These two sides are at a 90 degree angle to eachother. I know there is a formula to figure it out, but Algebra class was a long time ago, and I never took geometry. Can you tell me what the formula is?

In a right triangle (a triangle containing a 90 degree angle) the side opposit the 90 degree angle is called the hypotenuse and the othertwo sides are called the legs of the right triangle.
The formula you are looking for is c^2 = a^2 + b^2, where c is the hypotenuse and a is one leg and b is the other leg.
The simplest example is a right triangle that has leg a =3 and leg b=4. Then c^2 = 3^2 + 4^2 = 9+16 = 25. So c= sqrt(25) = 5.

Use the Pythagorean theorem. You are looking for the hypotenuse (side opposite the right angle). the formula is
h^2=10 1/6^2+15.25^2
h^2= 103.36111111111111111111111111111 +232.5625
h^2=335.92361111111111111111111111111
h=18.328'=18' 4"

ah! Pythagorean theorem! ok. this works for right triangles olny.
its a^2+b^2=c^2 or a squared plus b squared equals c squared.
a and b are the "legs" of the triangle. they form a 90 degree angle. c is the "hypotenuse" (yea, thats a fun word).
so the legs are:
a=12 2/12
b=15 3/12
so : (12 2/12)^2 + (15 3/12)^2 = c^2
then solve it...

This is probably the hard way, but you are looking for the length of the hypotenuse. The square of the hypotenuse is equal to the sum of the squares of the other two sides, so here goes: 10'2" = 122" squared = 14884, 15'3" = 183 squared = 33489, added = 48373, Square root = 219.94" = 18'4". I think.

The formula is Pythagoras' formula for the length of the "hypotenuse" or slant side of a right-angled trianle, c^2 = a^2 + b^2.
To get the most accurate answer, convert your feet and inches to whole numbers of inches instead of fractions of feet.
122^2 + 183^2 = 48373, sqrt(48373) = 219.9386... inches, that's 18 feet 3.9386... inches.

use pythagorean theorem where
a^2 + b^2=c^2
*in your case you've used degrees so make sure your answere is in degree form
if (10' 2")^2 + (15' 3")^2= c^2
then
c=18*5'16.26"
18*5'16.26"(* is supposed to be a degree sign) is the third side

c2=a2+b2
c is the side opposite to the right angle and a and b are the other 2 sides which join to make the right angle (a is usually the shortest side and b the middle, c would be the largest)

The measurement you are looking for is the Hypotenuse and is equal to the square root of the other two sides squared. 10'2" = 10.167 squared = 103.368. 15'3" = 15.250 squared = 232.563. Total = 335.931 square root = 18.328

Use pythagoras theoram
10^2+15^2=x^2
100+225=x^2
325=x^2
x=18
