Please help.

What is the value of x?

9.01 (I suppose you could say '9')

Step-by-step explanation:

Use pythagoras theorem. I will label the length CD as y, and I will use ✔ as square root.

First triangle.

a² + b² = c²

4² + 3² = y²

16 + 9 = y²

25 = y²

✔25 = y

y = 5

Second triangle (x)

5² + 7.5² = x²

25 + 56.25 = x²

81.25 = x²

✔81.25 = x

x = 9.01388

Disclaimer: I apologize if this is incorrect. I hope it helped!

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
