x =
can somebody please explain how this is supposed to be solved ?

Answer:
Step-by-step explanation:
70 + 70 + 2x = 180 ( angle sum property of trianlge}
2x = 180 - 140
2x = 40
x = 40 /2
x = 20
Answer:
x=20 degrees
Step-by-step explanation:
every triangle adds up to 180.
the pair of adjacent angle angles in the bottom corner make up 180
subtract the 110 from 180 you get 70
add the 70 and other 70 to get 140
subtract 140 from 180
ypou ghet your double x angle of 40
divide by 2
x=20
