Using the formula 1/x=1/y-1/z, express x in terms of y and z.

x=  yz/(z-y)

Step-by-step explanation:

Simplify the equation as below:

Bring x on left hand side and y & z on the right hand side.

\frac{1}{x} = \frac{1}{y}+\frac{1}{z}\\

\frac{1}{x} = \frac{(z-y)}{yz}\\

x = \frac{yz}{(z-y)}

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
