In a right triangle, A and B are the length of the legs, and C is the length of the hypotenuse. Use the pythagorean theorem to solve the following questions.
1. A= 15, B= 20
2. A= 2, B= 7
3. A= 20, C= 25
4. A= 8, C= 16

1) C=sqrt( 15*15 + 20*20 )= sqrt( 225 + 400)= sqrt (625)= 25
2) C=sqrt( 2*2 + 7*7 )=sqrt(4+49) sqrt(53)= 7.28
3) B= sqrt( 25*25 - 20*20) = sqrt(625-400)= sqrt(225)=15
4) B=sqrt( 16*16 - 8*8) = sqrt(256-64)= sqrt(192)=13.86

Plug and chug!
A^2 + B^2 = C^2
Now substitute from your problem and do the math!!!
