Question 1:
The angle m∠DOX is greater than 90 degrees, but less than 135 degrees.
Looking at the diagram we see that:
m∠DOX = 120 degrees.
Question 2:
The angle m∠COX is the sum of two angles that in total are 80 degrees.
Therefore, the equation is:
m∠COX = m∠AOX + m∠COA
Question 3:
The BOA angle measurement is given by:
BOA = 60 - 40
BOA = 20 degrees
Therefore, an angle that measures 20 degrees is:
BOA.
Question 4:
From the previous question we have:
m∠BOA = 60 - 40
m∠BOA = 20
The measure of m∠BOA is 20 degrees
Question 5:
The measure of the angle EOD is given by:
m∠EOD = 140 - 120
m∠EOD = 20 degrees
