We are given two expressions for angles in terms of \( x \):

1. \( 13x - 48^\circ \)
2. \( 7x + 36^\circ \)

If these two angles form a specific relationship, such as being supplementary (sum to \( 180^\circ \)) or complementary (sum to \( 90^\circ \)), we could set up an equation to solve for \( x \). I will assume that they are supplementary angles (sum to \( 180^\circ \)).

### Step 1: Set up the equation
Since the two angles are supplementary, we can write:
\[
(13x - 48^\circ) + (7x + 36^\circ) = 180^\circ
\]

### Step 2: Combine like terms
Simplify the left-hand side of the equation:
\[
13x - 48 + 7x + 36 = 180
\]
\[
(13x + 7x) + (-48 + 36) = 180
\]
\[
20x - 12 = 180
\]

### Step 3: Solve for \( x \)
First, add \( 12 \) to both sides:
\[
20x = 192
\]
Now, divide both sides by \( 20 \):
\[
x = \frac{192}{20} = 9.6
\]

### Step 4: Find the measure of each angle
Now that we know \( x = 9.6 \), substitute this value back into each angle expression:

1. \( 13x - 48^\circ \):
\[
13(9.6) - 48 = 124.8^\circ - 48 = 76.8^\circ
\]

2. \( 7x + 36^\circ \):
\[
7(9.6) + 36 = 67.2^\circ + 36 = 103.2^\circ
\]

### Final Answer:
- The first angle is \( 76.8^\circ \).
- The second angle is \( 103.2^\circ \).

These two angles sum to \( 180^\circ \), confirming they are supplementary.
