m∠BEC = 29°

m∠ABC = 122°

Step-by-step explanation:

∠BEC + ∠ECB + ∠CBE = 180

x + 93 + 2x = 180

3x = 180 - 93

3x = 87

x = 87/3

x = 29

∠BEC = x = 29°

∠ABC + ∠CBE = 180°

∠ABC + 2x = 180

∠ABC + 2(29) = 180

∠ABC + 58 = 180

∠ABC = 180 - 58

∠ABC = 122°

Answer:

39 ° ; 102 °

Step-by-step explanation:

2x° + x° + 93° = 180°

3x + 93 = 180

3x = 87

x = 29

m∠BEC = 29 °

m∠EBC = (2 × 29)° = 58°

m∠ABC + m∠EBC = 180°

m∠ABC = 180° - 58° = 122 °
