Answer:
z = 3
Step-by-step explanation:
Similar polygons have the ratio of their corresponding sides equal to each other. There:
9/z = 6/2
Cross multiply
z*6 = 9*2
6z = 18
z = 18/6
z = 3
9/20 is greater
9/20 = 0.45
..............
ASA we need a second angle that is next to the side
SAS we need a side next to the angle
