Find the size of angle MBD in the figure below
In the question, we first consider the triangle ACM.
we add the two angles ie 780 + 560 = 1340
we subtract from 180 to find the value of angle AMC.
180 - 134 = 460
angles AMC and BMD are vertically opposite angles and hence they are equal
we add the two angles in triangle MBD
46 + 62 = 1080
we subtract 108 from 180 to find the value of the third angle
180 - 108 = 720
we, therefore, have the value of angle MBD as 720
the value of angle MBD as 720
