plz give me the best answer.

Answer 1

78+3y=180

Answer 2

so It is 99?

Answer 3

no, that is the value of the other two unlabeled angles

Answer 4

because the two labeled angels are equal to each other, we could create an equation

Answer 5

78=3y

Answer 6

78=3y
/3 /3
y=26

Answer 7

therefore, the value of y is 26 and your answer is C. Does that make sense @thihaaung ?

Answer 8

incorrect ;(

Answer 9

but that is what the value is. because when you solve for y, that is the value that is recieved also because 26*3=78. However, if you are looking for the value of the adjacent angles, it would be 99 becuase both lines are parallel. So i suggest you try that one.

Answer 10

y=34

Answer 11

thanks for helped me ;)
