What are m<1 and m<2? Please help me

The rule for angles is that 115 and the angles right next to it, the ones that form the x, will equal 180. That means all you have to do is 115-180=65.

Another rule is that the interior angles of a triangle will be 180, so you add the angles we know in each triangle, 80+65+angle 1 = 180. If you do this correctly you should get angle 1 to be 35. Then you repeat on the opposite side except this time the angles are 85+65+angle 2 = 180. If you do this one correct you should get 30. Which makes your answer B.

Sorry if this is confusing the book will have better explanations than I can give.

Answer is

First, work out the angles around the center between the two triangles.

The angle opposite m115 is equal as they are opposite angles.
115+115=230
360-230=130
130/2=65

Again, both angles around the center point in both triangles will be 65 degrees as they are opposite angles.

Angles in a triangle add up to 180 degrees, so:
180-80-65 = 35 degrees for angle 1
180-85-65 = 30 degrees for angle 2
