Answer:
To find x, y, z, p and q, you need to know about the property of Rhombus.
13y + 10 = 7y + 16 (pair of equal opposite sides)
=> 6y = 6
=> y = 1
x = 7x + 16 (2 equal adjacent sides)
= 7*1 + 16
=23
z = 90 deg (angle between 2 diagonals)
q = 22 deg (isosceles triangle)
p = 90 - 22 = 68 deg (right triangle)
