Answer:
The correct solution is M = 110
m3 = 110°
Step-by-step explanation:
m1 = 180° - m4 ( sum of angles in a straight angle )
m1 = 180° - 150° = 30°
m3 = 180° - (m2 + m1) ← sum of angles in a triangle
m3 = 180° - (40 + 30 )° = 180° - 70° = 110°
Answer:1/4
1/2 is the same thing as 2/4 so.... 2/4 minus 1/4 is 1/4
