Find the measure of cd. round to the nearest tenth.

Therefore, mCD = 113.6°

Step-by-step explanation:

In the given triangle angle formed of the center will be defined by

= 0.8417

x = (0.842)

= 57.32°

Now angle formed at the center by CD will be = 2x ( 57.32 )

                                                                            = 114.64°

Therefore, mCD = 113.6°

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
