Achocolatier has 105 chocolates that he is going to put into boxes to sell. if 20 chocolates fit into a box, how many boxes will be filled?

105 ÷ 20 = 5, remainder 5

Five boxes will be filled, and 5 chocolates will be left over, which should not be left laying around so he should quickly eat them.

2.4

Procedure and explanation step by step:

1) Given that it is a right triangle you can use the trigonometric ratios.

2) The tangent is defined as: tan(Θ) = opposite-leg / adjacent-leg

3) opposite-leg = segment AB = 12

4) adjacent-leg = segment AC = 5

5) tan (Θ) = 12 / 5 = 2.4
