(33/14) / (105/28)...when dividing fractions, flip what u r dividing by, then multiply
33/14 * 28/105 = 132/210 reduces to 22/35 <==

A right angle has a league of 13 cm in the hypotenuse of 21 cm what is the length of the other leg
natta225 [31]
You can use c^2 = a^2 + b^2 to solve for the length of the other leg. Just substitute the values to the variable then transpose to get the value of the missing variable.

Given: a = 13; c = 21
Required: b - other leg
Solution:
   c^2 = a^2 + b^2
 21^2 = 13^2 + b^2
   441 = 169 + b^2
  b^2 = 272
  <span>√b = 16.49
    b = 16.49 cm</span>
