For number 15 and 16, you just have to find the absolute difference between the two points along the calibration of the protractor.

15. ∠BXC = |B - C| = |140° - 110°| = 30°
16. ∠BXE = |B - E| = |140° - 30°| = 110°

For numbers 20 and 21, apply the Angle Addition Postulate. This is when you add the individual interior angles to equate to the total angle.

20. ∠PQS = ∠PQR + ∠RQS
112° = 72°+ 10x°
x = 4

21. ∠KLM = ∠KLN + ∠NLM
135° = 47°+ 16y°
y = 5.5

Step-by-step explanation:

In the given-question, the information is missing. first, we declare the missing information, after that we define its solution:

Missing information:

plotting the Points (2, 0), (2, 4), (2, 1), and (2, -1).

solution:

please find the attachment.

In the given attachment file, all the points lie within the same line, which indicates its points, and the set may be interpreted throughout the form of (2,y), or even the points may also be placed on the line x=2.
