Answer:
11 3/7 hours
Step-by-step explanation:
The shorter candle burns faster, so the candles will not be the same height (0) until the taller candle burns completely. At 0.7 in/h, that will take ...
(8 in)/(0.7 in/h) = 80/7 h = 11 3/7 h
let f(r)=sin^3r/cos^3r
so f(-r)= (sin(-r)/cos(-r))^3
=(-sinr/cosr)^3
=-f(r)
so it is odd function

Step-by-step explanation:
1st angle = 2x
2nd angle = x
3rd angle = x - 8
Sum of the angles in a triangle = 180°
1st + 2nd + 3rd = 180°
2x + x + x - 8 = 180°
4x - 8 = 180°
4x = 188
x = 47°
Now substitute
1st angle = 2x = 2(47) = 94°
2nd angle = x = 47°
3rd angle = x - 8 = 47 - 8 = 39
Check: 94 + 47 + 39 = 180°
