1. The ratios for angles 35° and 50° have been left blank. Draw a right triangle with an acute angle of 35°, and measure the opposite and adjacent side lengths. Use these lengths to calculate the ratio for 35°. Repeat this process for 50°. Complete the table on the previous page.
   
   The ratio for 35° is approximately 0.70 and the ratio for 50° is approximately 1.19.
   
   

2. Use the table on the previous page to state a ratio of sides for each of the following triangles. Explain what each ratio represents.
   
   

   1. 
      
      The value produced when the length of the side opposite 25° is divided by the length of the side adjacent to 25° is 0.47.
      
      

   2. 
      
      The value produced when the length of side b is divided by the length of side a is 2.14.
      
   
   
   

3. Use the table on the previous page to determine the values of the variables.
