Step-by-step explanation:

To Make h  subject  of the formula

Step 1

: Cross multiply

Step 2 :

Use h to open the bracket

Step 3 :

Divide both sides by a +l to make h on one side of the equation

Step 4 :

Evaluate h+h = 2h

Divide both sides of the equation by 2

x= 149. 24+7=31. 180-31=149

your welcome

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
