Answer:
m∠ACD = 24°
Step-by-step explanation:
Measure of the interior angles of a polygon = [tex]\frac{(n - 2)\times 180}{n}[/tex]
Therefore, measure of the interior angles of a rectangle = [tex]\frac{(4 - 2)\times 180}{4}[/tex]
= [tex]\frac{360}{4}[/tex]
= 90°
m∠BCD = 90°
Since, m∠BCD = m∠BCA + m∠ACD
90° = 66° + m∠ACD
m∠ACD = 90° - 66°
= 24°
Therefore, measure of angles ACD is 24°.
