What is the length of the sides of kite ABCD? Find the lengths of side AB and side CD. AB = 20; CD = 15 AB = 15; CD = 20 AB = 9; CD = 16 AB = 24; CD = 25

AB = 15; CD = 20

Step-by-step explanation:

The question is attached.

A kite is a quadrilateral (four sides) with two pairs of equal sides which are adjacent to each other. A kite has two diagonals and the longer diagonal bisects the shorter diagonal.

We can use Pythagoras theorem to find the length of the kite sides:

AB² = 12² + 9²

AB² = 225

Taking square root of both sides:

AB = 15

AB = BC = 15 (adjacent sides of a kite are equal)

CD² = 12² + 16²

CD² = 400

Taking square root of both sides:

CD = 20

CD = AD = 20 (adjacent sides of a kite are equal)

B) AB = 15; CD = 20

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
