Lines x and y intersect to form angles 1,2,3, and 4. The measure of angle 3 is (3x - 9) and angle 4 is 111 degrees.

Can you help me make a equation

I think the equation is 3x-9 + 11 = 180

is this correct

Implied in the question is that angles 1,2,3,4 are in either clockwise or counter-clockwise order.

If that is true, then angles 3 and 4 are adjacent and supplementary (add up to 180°).

The proposed equation is correct *if the two angles are adjacent*:

3x-9 + 11**1** = 180

(note correction in typo).

¡çLMN and ¡çNMO are adjacent angles that share MN

as a side. Together, those two angles form ¡çLMO.

What equation can you write that shows the relationship between m¡çLMN , m¡çNMO , and m¡çLMO
