X is 10 ( equate both angles and solve)
M1. 43 degrees (plug x and solve)
M4. 60 degrees (definition of an equilateral triangle, every angle is 60 degrees)
M5. 60 degrees
M6. 60 degrees
M9. 43 degrees (plug x and solve)
M3. 180 degrees minus angle m4 = 120 degrees(looks like it too )
M2. 180-(43+120) = 17 degrees
M8. Pretty much m3 = 120
M7. Pretty much m2 = 17 degrees
I hope nothing wrong with my math but the logic should be sound !
Angle (2+5+7)= 180 - 2(43) = 94 degrees
Angle 2
