What is the measure of angle B in degrees?
B
А
112°
510

119°

I just did it on edg and got it right

∠B = 119°

Step-by-step explanation:

∠C + 112° = 180° (linear pair)

∠C = 180° - 112°

∠C = 68°

∠A + 51° + ∠C = 180° (angle sum property of a triangle)

∠A + 51° + 68° = 180°

∠A + 119° = 180°

∠A = 180° - 119°

∠A = 61°

∠B + ∠A = 180° (linear pair)

∠B + 61° = 180°

∠B = 180° - 61°

∠B = 119°

hope this helps you!
