Simple...

you have \frac{3}{8} and \frac{2}{5}

Just subtract...but first find a common denominator...

Use 40 as the common denominator...

\frac{3}{8} * \frac{5}{5} = \frac{15}{40}
and
\frac{2}{5} * \frac{8}{8} = \frac{16}{40}

So, subtract,

\frac{15}{40}
-
 \frac{16}{40}

=- \frac{1}{40}

Thus, your answer.

Answer: m<KHL = 37 degrees.

m<GHK = 53 degrees

Step-by-step explanation:

<CHD and <KHL are vertical angles. They are equal in measure. m<CHD is 37 degrees, so m<KHL is also 37 degrees.

Notice <GHL is a 90 degree angle (because the lines that form it are perpendicular) and <GHL is made up of two angles: <GHK and <KHL.

m<GHK + m<KHL (37) = m< GHL (90 degrees)

Subtract 37 from both sides.

m<GHK = 53 degrees
