Answer:
m1 = 62.5
m2 = 62.5
m3 = 55°
m4 = 75°
m5 = 50°
Step-by-step explanation:
m1: Sides 1 and 2 are congruent so angle will be the exact same as m2:
180° - 55° = 125 | 125 / 2 = 62.5°
m2: same as m1; 62.5°
m3: equivalent to 55° due to its location
m4: angle of a line is 180° so 180° - 105° = 75°
m5: angles of triangle add to 180° so 180° - (75° + 55°) = 50°
