Enter the unknown value that makes this statement true 20% of n is 120

600

Step-by-step explanation:

by dividing 120 by 20% or .2 we see that it is equal to 600

120/0.2=600

this can then be checked by multiplying 600 by .2 and getting 120

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
