The length of the line is 21.
Answer:
A) 12x-36=360 (equation to find x)
B) X=33
C) 71 for 3x-28 and 109 fo 3x+10
Step-by-step explanation:
So first we know tha there are vertical angles present (the opposite side of an angle directly)
And we also know the two sides since the two angle measures are just two different sides
If you add up all the 4 angle syou’ll get 360
So initially
3x-28+3x-28+3x+10+3x+10=360
Combine and get 12x-36=360
Now solve for X
7 because 7x3= 21 and 21 + the 7 cats comes to an equal 28
