Answer
Attempt 1 out of 2

m, angle, Cm∠C
be determined.

Answer 1

To find \( m \angle C \) in triangle \( DPZ \), we use the property of the angles in a triangle, which states that the sum of the interior angles in any triangle is \( 180^\circ \).

We are given:
- \( m \angle P = 39^\circ \)
- \( m \angle D = 113^\circ \)

Let's denote \( m \angle C \) as \( x \).

The equation for the sum of the angles in triangle \( DPZ \) can be set up as:

\[
m \angle P + m \angle D + m \angle C = 180^\circ
\]

Substituting the known values into the equation:

\[
39^\circ + 113^\circ + x = 180^\circ
\]

Now, add \( 39 \) and \( 113 \):

\[
152^\circ + x = 180^\circ
\]

Next, we can find \( x \) by isolating it:

\[
x = 180^\circ - 152^\circ
\]

\[
x = 28^\circ
\]

Thus, the measure of angle \( C \) is:

\[
\boxed{28^\circ}
\]
