Draw out these two triangles on your paper and show all of your work to prove whether or not they are similar. Then take a picture of your work and put it here.

These triangles are...

What is the value of x?

The value of x is?

What ratio is the tan(C)?

Select the correct multiple choice option based on the work you did for problem 21.

Use the appropriate trig ratios to solve for the value of x.

Steps:

1.) Label the triangle with hyp, opp, adj.

2.) Determine which trig to use

3.) Set up equation

4.) Swtich the x and the fraction.

5.) Use the correct inverse trig function in the calculator.

Then, take a picture of your notes and place them here.
