What is the length of the unknown leg in the right triangle?
8cm 16cm 20cm 40cm

c

Step-by-step explanation:

the formula is a^2+b^2=c^2 so one leg is 21 so a+ 21^2=29^2. Then you square both and get a+441=841. Then you subtract 441 from both sides and get 400. You square 400 and get 20.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
