Use the diagram shown. Solve for x. Find the angle measures to check your work. mZAOB = (9x - 5)º
mZBOC = (2x +11°
mZCOD = (6x + 10°
X=

x = 5

Step-by-step explanation:

From the picture attached,

It's given that ∠AOB ≅ ∠COD

therefore, m∠AOB = m∠COD

Now from the given measures of the equal angles,

9x - 5 = 6x + 10

9x - 6x - 5 = 10

3x - 5 = 10

3x = 10 + 5

3x = 15

x =

x = 5

Therefore, measure of the angles given in the picture will be,

m∠AOB = (9x - 5)° = 40°

m∠BOC = (2x + 11)° = 21°

m∠COD = (6x + 10)° = 40°

i would say c is the best answer, hope it's right!

good luck! =)
