Please mark me as brainlist

Step-by-step explanation:

In rectangle diagonals are equal and bisect each other at 90 degrees

EC= 1/2Ac

EC=1/2(12x-16)

EC=6x-8

EC=BE (AC=BD)

6x-8=4x+2

6x-4x=8+2

2x=10

x=5

EC=6×5-8

EC=30-8

EC=22 unit

20)

Y=12 [adjacent sides of kites are equal]

X=21 [adjacent sides of kites are equal]

In kite diagonals bisect each other

Angle 5 =20

Angle 4=70. [180-(90+20)]

Angle 3=42. [Angle opposite to equal sides are equal]

Angle 2=48

Angle 1= 90. [IN kites diagonals cut each other at 90 degrees]
