Here I want to show you how to do some of our homework for today and this are the question that Mr. Harbeck gave us:

In this one the hypotenuse is the 50 and the leg a is number 30 we had to find what was the letter b: there in the picture a square + b square = c square
then b square + 30 square = 50 square and
b square then you cancel the 30 square in the left side then 50 - to the square that you cancel in the other side and b square = 50 * 50 - 30*30
b2 = 2500 - 900
b=40 or the square root of 1600 is the number 40

This question is the same i the other one you had to put always the formula which is a square + b square = c square then solve the problem b square + 6 square =10 square , then cancel the 6 square then you had to minus the 6 square to the 10 square and this what will be it look like b2 = 10*10 -6*6,b2=100-36 and b2= 64 and the root of the number 64 is 8 so the b is number 8

In this picture my work is the same to the other 2 we had to find the letter b
A2+B2 =C2,then b2 + 17 square which is the letter a
b square = 32*32-17*17
b2=1024-289 then we subtract the 1024 to the 289which is 735 then we had to find which was the root of the number 735 and this is 27.11 or b=27.11

and this is my scribe pls! leave a comment and pls! be understandable sorry for my mistakes

I'm impressed you are reteaching me my old math. The pictures along with the formula break down is easy to follow.
