Answer:

x = 100

Step-by-step explanation:

I know that the total is 180 so with that in mind this is what i did to get the answer.

180 - 57 = 123

123 - 23 = 100

Double check your work

100 + 23 = 123

then 123 + 57 = 180

your answer is 100:)

hope this helped!

Answer:

100 because, the bottom line is 180 degrees so do 180-57 which would equal 123 then do 123-23 and there's your answer 100.
