Question

In Rectangle ABCD, m

Answer 1

Answer:

m∠ACD = 24°

Step-by-step explanation:

Measure of the interior angles of a polygon = $\frac{(n - 2)\times 180}{n}$

Therefore, measure of the interior angles of a rectangle = $\frac{(4 - 2)\times 180}{4}$

                                                                                              = $\frac{360}{4}$

                                                                                              = 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°.
