Remember that
![\tan\theta=\dfrac{\sin\theta}{\cos\theta}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7B%5Csin%5Ctheta%7D%7B%5Ccos%5Ctheta%7D)
So if
and
, then we know
.
Then use the Pythagorean identity to solve for cosine:
![\cos^2\theta+\sin^2\theta=1\implies\cos\theta=-\sqrt{1-\sin^2\theta}=-\dfrac{2\sqrt{10}}7](https://tex.z-dn.net/?f=%5Ccos%5E2%5Ctheta%2B%5Csin%5E2%5Ctheta%3D1%5Cimplies%5Ccos%5Ctheta%3D-%5Csqrt%7B1-%5Csin%5E2%5Ctheta%7D%3D-%5Cdfrac%7B2%5Csqrt%7B10%7D%7D7)
In order to calculate the number of loaves Roger can bake, we should calcculate how many times 3/4 (required butter for one loaf of bread) is included in 2 1/2 (amount of butter Roger has).
2 1/2=4/2+1/2=5/2
(5/2)/(3/4)=5*4/2*3=20/6=3,33
Roger can bake 3 loaves of bread.
