On december 1 at 10 p. m., the bright star procyon will just be rising on the eastern horizon. at approximately what time would you see this star rising on christmas day (24 days later)?

8 : 24 P.M

Step-by-step explanation:

Data provided in the question:

On December 1 bright star Procyon will just be rising on the eastern horizon at 10 P.M

Now,

we know that Stars rise 4 minutes earlier each night

Therefore,

24 days later i.e after 24 nights the total early time

= 24 days × 4 minutes per day

= 96 minutes

or

= 1 hour 36 minutes early

Hence,

on Christmas Day the star will rise at 1 hour 36 minutes early than 10 P.M

= 8 : 24 P.M

what the question so we can you out

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
