Use the angle addition postulate to create and solve and equation for each situation.

Question

m∠AOB = 28, m∠BOC = 3x-2, m∠AOD = 6x
m∠AOB = 4x+3, m∠BOC = 7x, m∠AOD = 16x-1

I don't know what to do. so don't got an answer to share

Answer 1

add up the measures of adjacent angles to get the measure of the sum

You do not provide any information on how these angles are related.

Answer 2

so m∠AOB = 28, m∠BOC = 3x-2, m∠AOD = 6x. x = 18

Answer 3

yes, but which angles are inside which others? I can think of several ways to solve for x, but they depend on where ABCD are located.
