Answer:
s = 130 degrees
Step-by-step explanation:
decagon has a 1,440 degrees interior angles
equation: 1,440 = s + 1310
to find s, add all the known angles
⇒ s + 150 + 170 + 160 + 130 +120 + 160 + 105 + 160 +155
⇒ s + 1,310
equation:
s + 1310 = 1440
subtract each side by 1310
⇒ s + 1310 - 1310 = 1440 - 1310
⇒ s = 130

Answer:
   (-1/4, 2)
Step-by-step explanation:
Substitute the given information into the equation and solve for y.
   3y +4(-1/4) = 5
   3y -1 = 5 . . . . . . simplify
   3y = 6 . . . . . . . . add 1
   y = 2 . . . . . . . . . divide by 3
The point is (-1/4, 2).
