Question 1)

Please here you have to solve this equation:

45 = 23 +x, then x= 45 -23 , so x= 22 degrees

Question 2)

here plese note that you have to solve this equation:

72 + y = 180, then y= 180 - 72 , or y= 108 degrees

Question 3)

here we can write:

4x - 20 + 2x -10 + 180 - 5x = 180

x - 30 =0 so, x= 30 degrees

Question 4)

since <A= 62 degrees, we have:

1) BC, 2) AB, 3) AC

Question 5)

here we have:

1) <V, 2) Q, 3) <X

Question 6)

1) DE, 2) CB, 3) GB, 4) FG, 5) EF, 6) DC

Bonus Question)

here I apply the theorem of external angle in a triangle, and I can write:

<CMB = <CAM + <ACM

so I get:

<CMB is greater than <CAM so I can write:

AC is greater that CM, since the side opposite to the angle <CMB is AC
