Trig and geometry: the area, perimeter and size of a cyclic quadrilateral

Please help

ABCD is a cyclic quadrilateral with <DAB=100º, AB=7cm and BC= 8cm

i) the size of <BCD
ii) the size of <ADC
iii)the perimeter of the quadrilateral
iv)The area of the quadrilateral

I know that in geometry, a cyclic quadrilateral is a quadrilateral whose vertices all lie on a single circle.

Help is greatly appreciated

Please check the question. It's impossible to answer with the information you've given (except for part (i), which is ). There are infinitely many cyclic quadrilaterals with different shapes and sizes that can be drawn with these dimensions.
