Please here you have to solve this equation:
45 = 23 +x, then x= 45 -23 , so x= 22 degrees
here plese note that you have to solve this equation:
72 + y = 180, then y= 180 - 72 , or y= 108 degrees
here we can write:
4x - 20 + 2x -10 + 180 - 5x = 180
x - 30 =0 so, x= 30 degrees
since <A= 62 degrees, we have:
1) BC, 2) AB, 3) AC
here we have:
1) <V, 2) Q, 3) <X
1) DE, 2) CB, 3) GB, 4) FG, 5) EF, 6) DC
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
