Answer: 
Step-by-step explanation:
All radii of a circle are congruent, so by the base angles theorem
Also, angles x and y are inscribed in the same arc, and they are thus congruent, meaning x = 65.
Answer:
none
Step-by-step explanation:
There is not a given angle side angle or a side angle side (no two angles and no two sides) so no to the first two.
HL includes two given side, which one must be the hypotenuse, and a right angle so no to that one.
The answer is 2.5 just set it up and cross multiply then divide
