hope this helps! :D
![110 = 11 \times 10](https://tex.z-dn.net/?f=110%20%3D%2011%20%5Ctimes%2010)
![110 = 11 \times \ 5 \times 2](https://tex.z-dn.net/?f=110%20%3D%2011%20%5Ctimes%20%5C%205%20%5Ctimes%202)
So it is the product of
![5 \times 2 \times 11](https://tex.z-dn.net/?f=5%20%5Ctimes%202%20%5Ctimes%2011)
And 2,5 and 11 are prime numbers, so there you go :)
Step-by-step explanation:
![\cos 90 \cos 30 + \sec^2 45 \sin 30 - \cos 270 \sin 180](https://tex.z-dn.net/?f=%5Ccos%2090%20%5Ccos%2030%20%2B%20%5Csec%5E2%2045%20%5Csin%2030%20-%20%5Ccos%20270%20%5Csin%20180)
But we know that
![\cos 90 = \cos 270 = \sin 180 = 0](https://tex.z-dn.net/?f=%5Ccos%2090%20%3D%20%5Ccos%20270%20%3D%20%5Csin%20180%20%3D%200)
and
![\sin 30 = \dfrac{\sqrt{3}}{2} \:\:\text{and}\:\: \sec 45 = \sqrt{2}](https://tex.z-dn.net/?f=%5Csin%2030%20%3D%20%5Cdfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%20%5C%3A%5C%3A%5Ctext%7Band%7D%5C%3A%5C%3A%20%5Csec%2045%20%3D%20%5Csqrt%7B2%7D)
so this leaves us with just
![\sec^2 45 \sin 30 = (\sqrt{2})^2 \left(\dfrac{\sqrt{3}}{2} \right)= \sqrt{3}](https://tex.z-dn.net/?f=%5Csec%5E2%2045%20%5Csin%2030%20%3D%20%28%5Csqrt%7B2%7D%29%5E2%20%20%5Cleft%28%5Cdfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%20%5Cright%29%3D%20%5Csqrt%7B3%7D)
