How can I select tools and techniques to analyze the relationship among the sides of a right triangle

3 0

If it is a special triangle (either 45-45-90 or 30-60-90) then you select the tools from the rules of special triangles.

Otherwise, if you know two angles and a side of the triangle (AAS or ASA) you use law of sines. If you know two sides and an angle (SSA) you can also use law of sines.

Use the law of cosines when you know two sides and the angle in between them (SAS).

In that period, he practices 6 different songs, spending an equal amount of time on each one.

This means that each song gets the sixth part of the lesson duration. The fraction that expresses that amount is:

$\displaystyle \frac{\frac{3}{4}}{6}=\frac{3}{24}=\frac{1}{8}$
