Answer:
Answer choice 'A'
Step-by-step explanation:
since the rightmost angle is 63°, then, the one across it has to equal 63°.
[tex]63 - 23 = 40[/tex] then y=40°. the only answer choice that would be correct would be 'A', but if you want to double check, a line has to equal 180°.
[tex]180-63=117[/tex]. So, [tex]2(67)=134[/tex] then [tex]134-17=117[/tex]. So both parts of the answer choice are right
