Y=18 is the correct answer
The angles in a quadrilateral must add up to 360 degrees. So, if we add up the first three sides we get 77 + 180 + 65 = 322 degrees. The last side is going to be 360 - 322 = 38 degrees.
Answer:
(- 4, - 2 )
Step-by-step explanation:

a point (x, y ) → (- y, x ) , then
(- 2, 4 ) → (- 4, - 2 )
Answer:
Step-by-step explanation:
Distance = 140 - (-40)
