Answer:
900 degrees
Step-by-step explanation:
Use the formula for interior angles
Sum = (n - 2) x 180
Sum = (7 - 2) x 180
Sum = 5 x 180
Sum = 900 degrees

Answer:

Step-by-step explanation:
slope is the change in y over the change in x.
change in y is 14-18= -4
change in x is 30-(-20)= 50
so the answer is -4/50
we can factor out 2 from both equations to simplify the fraction. this gives us -2/25
Answer:
Side MN = 3.5
Step-by-step explanation:
Side NO = 1.2011
Side OM = 3.3
Side MN = 3.51179
Angle ∠M = 20° = 0.34907 rad = π/9
Angle ∠N = 70° = 1.22173 rad = 7/18π
Angle ∠O = 90° = 1.5708 rad = π/2
