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°

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
