Given: medf = 120°; madb = (3x)°; mbdc = (2x)°prove: x = 24what is the missing reason in step 3? vertical angles are of congruencydefinition of equality

Please find the attachment for the accompanying diagram of this question. From the diagram we can see that and are vertically opposite angles.

Thus,

Now, we know that the value of =120 degrees (given)

We also know that is the sum of two angles, and , thus we have:

120= +

Now we are given that =3x and =2x, thus the above equation becomes

therefore x=24

Thus we have proved that x=24 degrees as required
