Answer:

12 m

Step-by-step explanation:

This can be solved using the Pythagorean theorem

a^2 = b^2 + c^2

20^2= 16^2 + c^2

400= 256 + c^2

400-256= c^2

144 = c^2

c = √144

c= 12

Ksju [112]

Step-by-step explanation:

you did not even try a calculator to find the result ?

64 is 8×8 or 8².

so, sqrt(64) = 8.

similarly for 4 :

4 is 2×2 or 2².

so, sqrt(4) = 2

so,

sqrt(64)/ sqrt(4) = 8 / 2 = 4

so, d. is the right answer.
