Answer:
x = 22, and im rlly sry, i dont know how to solve for y...im sry...
Step-by-step explanation:
180 - 55 = 125 degrees
so
6x - 7 = 125
<u> +7 +7</u>
6x = 132
divide by 6
<u>x = 22</u>
This is the number of combinations of 2 from 23
23C2 = 23! / 2! 21!
A quick way to do this is 23*22 / 2 = 253
