1. what is the measure for the following ∠? m∠dox? 40 80 120 2. m∠cox = m∠aox + m∠ cox coe coa cod 3. which of the following angles has a measure of 20 degrees? ∠aox ∠aoc ∠boa 4. what is the measure for the following ∠? m∠boa? ? 20 40 60 5. what is the measure for the following ∠? m∠eod 20 120 140

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
