△BCE∼△JKL. If m∠B=89°, m∠C=13°, and m∠E=78° what is m∠J?(1 point) m∠J=

89°

Did you know?

m∠J=90°. Did you know that in a triangle, the sum of the interior angles always equals 180°? Therefore, in this triangle △BCE, we can find the measure of angle J by subtracting the measures of angles B, C, and E from 180°. Given that m∠B = 89°, m∠C = 13°, and m∠E = 78°, we can calculate m∠J as follows: m∠J = 180° - (m∠B + m∠C + m∠E) m∠J = 180° - (89° + 13° + 78°) m∠J = 180° - 180° m∠J = 0° However, we notice that the answer doesn't make sense since a triangle's interior angles cannot add up to 0°. Upon further inspection, we realize that there is a typo in the given information. The angle measures for △BCE must be incorrect since they do not add up to 180°. Therefore, it is not possible to determine the measure of angle J based on the provided information.
