Answer:
20 cm
Step-by-step explanation:
8/2 = 4
6/2 = 3
3 and 4 are the sides of the triangle (four triangles in rhombus)

c = 5
5 x 4 = 20
Hope that helped!!! k
HA stands for Hypotenuse Angle theorem.
This is a special case of b. AAS theorem
This is because you would be given a side length ( hypotenuse and an acute angle). and since we would already know that a right triangle has a right angle, so we would have 2 angles and a side = AAS.
W is 38 to form a right angle
Z is 29 for the same reason
Y is 52 because of vertical angles
