Answer:
M1= 35° M2=30°
Explanation:
At the point where the two triangle meet, the north angle is 115°, so the south one will be 115°, because they're alternate angles. This means that to get the other two angles left, you must subtract the two angles that weren't in the triangles on that point = 360° - (115 x 2) = 130°. 130° is the total of the two angles on the point in the two triangles. Then you just subtract the two angles you have for each triangle from 180° to get the last two angles
