Finding an angle of a triangle
If there are 24 hours a day, he hangs out 8 hours a day since 24-8-8=16
All activities are eqyal to 8/24, which simplifies to 1/3.
1/3 as a percent is 33.33...%
He should include 33.33..% three times in his circle graph.
U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2
The answer is 31
29 - 13 is 16
16 + 15 is 31
