Use the geometric mean (leg) theorem. what is the
value of a?
7 sqrt 2
2 sqrt 70
20 sqrt 5
70 sqrt 5

i dont know

step-by-step explanation:

i believe the answers 600m

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
