FOR 21 POINTS

A triangle has an angle measuring 90°, an angle measuring 20°, and a side that is 6 units long. The 6-unit side is in between the 90° and 20° angles.


How many unique triangles can you draw like this?

Answer:

One

Step-by-step explanation:

     Since we have a 90° angle and a 20° angle, the last angle must be 70°.

180° - 90° - 20° = 70°

     Now we also have the requirement of a 6-unit side between the 90° and 20° angles.

     With all of these requirements, we can only draw one triangle like this since we have an angle, an angle, a required third angle, and a side.
