ABCD is a rectangle and OA is perpendicular to OB BCI=2cm, (CD) = 6cm and tanxdegree .find the values of a)sin x b) Cost x C)line OZ

its d. the first coordintaes are 10,32

step-by-step explanation:

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

step-by-step explanation: there is no picture

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
