Answer: y=17 x=10
Step-by-step explanation:
so they have equal measures and they’re a linear pair (make a line) and a line is 180° so that would means you can set both equal to 90°
9y-63=90 and 9x=90
so for the first one you subtract 63 from 90 then divide by 9 to get 17
the next one you just divide by 9 to get 10 therefor y=17 and x=9
