You have to explain how you knew to use 55 and 120, not another option.
Hope it helped! :)
Answer:52.0
Step-by-step explanation:you just add a decimal then a 0 because it is a whole number
The Figures that are shown in the diagram are
Ray CD
and
Segment CD
6x+1 = 12x because the Z angles are the same
Solve this and you get:
1 = 12x - 6x => x = 1/6
