Question

Two intersecting lines, create four angles with the same vertex labeled a B C, and D angle B is adjustment to a and C find M AFMC equals
75
180
105
15

Answer 1

If angles B and C intersect at vertex A, then angle BAC and angle CBA are vertical angles and they are congruent. Similarly, angle CAD and angle DAB are also vertical angles and congruent.

Therefore, angle B = angle C and angle D = angle A.

If angle B = 75°, then angle C is also 75° because they are congruent.

Since angle B + angle C = 75° + 75° = 150°, the remaining two angles (angle A and angle D) must sum to 180° - 150° = 30°.

However, none of the given answer choices match 30°, so it seems there might be a mistake in the question or answer choices provided.
