If 75+40 equal 115, and triangles always add to 180 degrees, than 180-115 equals 65. 65 degrees should be the answer.

Answer:

Step-by-step explanation:

75+40+x=180(sum of angle of a triangle)

or,115+x=180

or,x=180-115

   x=65

now,

x+y=180(being straight line)

or,65+y=180

or,y=180-65

   y=115
