The figure below is a rhombus.
z = [ ? 10

Answer:
27 degrees
Step-by-step explanation:
one property of a rhombus is that the diagonals makes an 90 degree angle. so x= 90 degrees. the angle above x is also 90 degrees as well and since angles in a triangle add up to 180, we do 180-63-90, to get z which is 27 degrees
