Using the Sine Rule:-
20 /sin 45 = BC / sin 30
BC = 20 sin 30 / sin45
= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer
1/5 of 55 is 11, you multiply 11 by 20 and you get 220. Total there is 1100 minutes of tv so then you subtract 220 from 1100 and there is 880 minutes of tv without commercials then you divide that by 60 and you get 14 hours and 20 minutes.
