SOLUTION: ABCD is a kite AD 6.4 CM DC 9.7 CM ANGLE ADC = 110 DEGREES WORK OUT THE AREA THANK YOU

To find the area of triangle ADC, we can use the formula:

"The area of a triangle is one-half the product of two
sides multiplied by the sine of the angle between those
two sides."

So,



Calculate that with what you're given and then multiply what
you get by 2 since the area of the kite is twice the area of 
triangle ADC.
