Figure tvwx is a square. which statement is not necessarily true?

a.

b.

c.

d.

A.

Step-by-step explanation:  In the given figure TVWX is a square, properties of square are:

(i)  All sides equal.

(ii)  All angles equals to 90°.

(iii) Diagonals are equal and bisect each other at 90°.

Here,

A.    is not true because diagonal of the square cannot be equals to the side of a square.

B.   is true because these are the sides of square.

C. because each angles of square are equal to  90°.

D.   because each angles of square are equal to 90°.

∴ A. is not true.

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
