So what you would do is 42 + 1:33 = 2:15

Then you would add 2:53 to 2:15 which will be 5:08. So the final step will to subtract 5:08 from 8:01 which will be 2:53 P.M

**Answer:**

11. x= 117 and y =57

12. 9

13. 900 degrees

**Step-by-step explanation:**

11. Y can be found using supplementary angles. 123+y = 180 since they form a straight line. This means y=57. The inside of a quadrilateral is equal to 360 degrees. This means 117+69+57 +x=360. Then 243+x=360 and x= 117.

12. The exterior angles of a polygon with n sides is 360/n. Since we don't know n but we do know the angle is 40 degrees, we write 360/n=40. Solve for n.

360/n=40

360=40n

360/40=n

n= 9

13. This figure is a regular sides polygon. It has 7 sides and therefore 900 degrees.
