Answer:
< DGB = 101
Step-by-step explanation:
< CGB is equal to 79
< CGB is another name for < 1
We want to find < DGB which is another name for <2
< 1 and < 2 are a linear pair
<1 + <2 = 180
79 + <2 = 180
<2 = 180-79
<2 = 101
The answer is 101
Since a line has an angle of 180°
To know DGB we will just subtract 79 from 180
hence DGB=180°-79°
=101°
