Answer:

x = 4

Step-by-step explanation:

x has the same value as RT since they are equal sides of the isosceles triangle.

RT is also the hypotenuse of ΔRST - 30°×60°×90° right triangle.

Acoording to the property of such triangles, the ratio of sides is:

a : b : c = 1 : √3 : 2

We have:

b = 2√3 and c = RT

Use the ratio to find the lenght of RT

2√3 : RT = √3 : 2
RT = 2*2√3/√3
RT = 4

So the value of x is 4 units

Answer:

The area of the black portion = 219.752280681013 cm²

Step-by-step explanation:

the canvas has the shape of a square

with sides of length 8×4 = 32 cm

Then

• The area of the canvas

= 32²

= 1024 cm²

•• The area of the four circles

= 4×(π×8^2)

= 804.247719318987 cm²

••• The area of the black portion

= 1 024 - 804.247719318987

= 219.752280681013 cm²
