image shows two lines, a c and d b, which intersect in the point o. the measure of a o b is 91 degrees.

column a says measure of angle a o d. column b says measure of d o c.
A. The quantity in Column A is greater.
B. The quantity in Column B is greater.
C. The two quantities are equal.
D. The relationship cannot be determined from the information given.

Answer 1

Now I understand the problem.

Answer 2

What is the measure of x? (Hint: remember vertical angles.)

Answer 3

91!

Answer 4

well i g2g but plz tell me the answer and how to understand it :(

Answer 5

Great.

What's the measure of angle y?
(Remember that 91 and y are a linear pair and supplementary.)

Answer 6

Once you get y, then you have one more angle, which is z. z is vertical with y, so their measures are equal.

Answer 7

Now look at your original figure and see where the angles are and you can answer the question.

Answer 8

its B?

Answer 9

the way they are phrased is confusing to me

Answer 10

Correct.

Column A Column B
m<AOD = 89 m<DOC = 91
smaller angle larger angle
