Two intersecting lines create four angles with the same vertex, labeled A , B , C , and D . Angle B is adjacent to ∠A and ∠C . Find m∠A if m∠C=75° .(1 point) Responses 75° 75 degrees 15° 15 degrees 105° 105 degrees 180°...
Since angles A and C are adjacent to angle B, their measures must add up to 180 degrees.
Let m∠A be x.
m∠C is given as 75°.
So, x + 75° = 180°.
Simplifying the equation, we get:
x = 180° - 75°
x = 105°
Therefore, m∠A is 105°.
