Question

Find the value of x:

Find the value of y:

Find the perimeter of Kite ABCD:

Answer 1

the answer is D if it is not then try A

Answer 2

Answer:

Step-by-step explanation:

DE² = 29² - 21² = (29+21)(29-21) = 50*8 = 400

DE =√400 =  20

x = DE  {in Kite, diagonal AC bisect DB. DE = EB}

x = 20

DC² = DE² + EC² = 20² + 99 ² = 400 + 9801 = 10201

DC = √10201 = 101

y =101

In Kite, adjacent sides are equal.

AD = AB = 29

CD = CB = 101

Perimeter = 29 + 29 + 101 +101 = 260
