Question

Which cannot be the angle measurements of triangle ABC? OmZA = 55°, mZB = 65°, mZC = 60°
OmZA = 60°, mZB = 60°, mC = 60°
MZA= 57°, MZB = 58°, mZC = 65°
MZA = 61°, mZB = 57°, mZC = 61°​

Answer 1

Answer:

Last option is the correct answer.

$m\angle A = 61°, m\angle B = 57°, m\angle C = 61°$

Step-by-step explanation:

Since, 61° + 57° + 61° = 179° < 180°

Therefore,

$m\angle A = 61°, m\angle B = 57°, m\angle C = 61°$ cannot be the measurements of triangle ABC.
