Two intersecting lines create four angles with the same vertex, labeled A, B, C. and D. Angle B is adjacent to LA and LC. Find m L A if m/C = 75°
- (7 point)
Since angles B and C are adjacent to angle A, it means that angles B and C share a common side with angle A.
Therefore, angle A is adjacent to angles B and C as well.
Given that m/C = 75°, we know that angle C measures 75°.
Since angles B and C are adjacent to angle A, we can conclude that angle A also measures 75°.
