The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary.

leg: 32 m; hypotenuse: 38 m

26.8 m

20.5 m

49.7 m

26.6 m

32^2 + x^2 = 38^2
1024 + x^2 = 1444
-1024 -1024
x^2= 420
x=20.493901532

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
