Answer:
There are (63) combinations. The notation means "six choose three". Out of six items (flavors) choose three.
(nk)=n!k!(n−k)!.
(63)=6!3!3!.
Think of it this way. There are 6 ways to choose a flavor. Once you choose, there are 5 ways to choose the next. After that, there are 4 flavors left. which is 6!/3!=6⋅5⋅4⋅3⋅2⋅13⋅2⋅1=6⋅5⋅4=120.
But, you could have chosen {chocolate,vanilla,strawberry} and you get the same combination as {vanilla, strawberry, chocolate} so we have to divide by 3!=3⋅2⋅1=6 to account for the order of choosing.
So the number of combinations of flavors is (63)=1206=20.

<em>Angle </em><em>ADG,</em><em> </em><em>angle</em><em> </em><em>BEH </em><em>and </em><em>angle</em><em> </em><em>CFI,</em><em> </em><em>all </em><em>have </em><em>two </em><em>curves</em><em> </em><em>in </em><em>their</em><em> </em><em>angles</em><em>.</em><em> </em><em>Same </em><em>number</em><em> of</em><em> </em><em>curves</em><em> </em><em>are </em><em>used</em><em> </em><em>to </em><em>represent</em><em> </em><em>that </em><em>their</em><em> </em><em>measure</em><em> </em><em>are </em><em>equal</em><em>.</em><em> </em>
So, m angle CFI = m angle ADG
So, m angle CFI = m angle ADG=> m angle CFI = 92°
