I need help with number 1 and number 3.

1. First, set up a ratio to find the length of WZ. Use the lengths that are already given to you.
[tex]\frac{2}{6} = \frac{3}{x} \\x = \frac{3(6)}{2}\\x = 9[/tex]
D is the correct answer for 1.

3. The key word to notice here is that the pentagons are SIMILAR. This means that they have corresponding angles that are EQUAL.
This tells us that angle x must also be 60 degrees.
B is the correct answer for 3.
