Properly formula based step solved
That easy just divide 9 by 22 if need simplify it
Looks like all real numbers except 1. It touch's all the y except 1 aka range
20 laps at 400 yds per lap = (20 x 400) = 8000 yds
1680/8000 = 0.21....multiply by 100 to get ur percent (100 x 0.21) = 21%
Answer:
d. 8°
Step-by-step explanation:
It appears as though you intend ∠ECF and ∠ACB to be vertical angles, hence the same measure, 47°. The angle of interest, ∠BCD, is added to that to make ∠ACD, which is 55°. The added angle must be 55° -47° = 8°.
