Question

In Rectangle ABCD, m

Answer 1

m∠ACD = 24°

Explanation:

Measure of the interior angles of a polygon =
`((n - 2)* 180)/(n)`

Therefore, measure of the interior angles of a rectangle =
`((4 - 2)* 180)/(4)`

=
`(360)/(4)`

= 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°.
