What is the frequency of a light wave with a wavelength of 3.2x10-9 m? show work

Step-by-step explanation:

The sum of the interior angles of any triangle is 180 degrees.

Thus, 59 degrees + 72 degrees + x = 180 degrees, or

131 degrees + x = 180 degrees.

Subtracting 131 degrees from boths sides isolates x:

x = (180 - 131) degrees, or

x = 49 degrees

x and y are "straight angles;" their sum must be 180 degrees.  Thus, y = (180 - 49) degrees, or y = 131 degrees.

Similarly, w + 72 degrees must add up to 180 degrees, so w = 108 degrees.
