Answer:
The answer to this is False, False, True.
Step-by-step explanation:
A is false because WAU is an obstute angle, which can't be 55 degree.
B is flase because YAU is actually the angle that is 55 degree, not 35 degree.
C is true because WAX is congruent to YAU and it is 55 degree.
The first is 6 and then the second one is 5
