Trigonometry Tables

We are working on trigonometry, and have explored right angle triangles with a 30 degree angle.  We noticed that the sides of the triangles have consistent ratios.

Some of you asked if triangles that have angles other than 30 degrees have similar proportions.  Here’s a table of all of the ratios.  Don’t worry, you don’t have to memorize any of this.

 Here’s your homework question.  Try it using the tables and also try it with your calculator.  Remember to put your calculator into degree mode.
