<span>B) A key chain can hold 3 keys. If there are a total of 12 keys, how many key chains are there?</span>
Acute
Angle ∠ A = α = 25.385° = 25°23'6″ = 0.443 rad
Angle ∠ B = β = 73.004° = 73°14″ = 1.274 rad
Angle ∠ C = γ = 81.611° = 81°36'41″ = 1.424 rad
In 3 hours, they could bake 87 birthday cupcakes. If you divid 145 by 5 this gives you 29, and you multiply this by 3 to find how many can be made in 3 hours, which gives you 87:) hope this helps!
