Solution

We are given two expressions for angles in terms of xx:

  1. 13x4813x - 48^\circ
  2. 7x+367x + 36^\circ

If these two angles form a specific relationship, such as being supplementary (sum to 180180^\circ) or complementary (sum to 9090^\circ), we could set up an equation to solve for xx. I will assume that they are supplementary angles (sum to 180180^\circ).

Step 1: Set up the equation

Since the two angles are supplementary, we can write: (13x48)+(7x+36)=180(13x - 48^\circ) + (7x + 36^\circ) = 180^\circ

Step 2: Combine like terms

Simplify the left-hand side of the equation: 13x48+7x+36=18013x - 48 + 7x + 36 = 180 (13x+7x)+(48+36)=180(13x + 7x) + (-48 + 36) = 180 20x12=18020x - 12 = 180

Step 3: Solve for xx

First, add 1212 to both sides: 20x=19220x = 192 Now, divide both sides by 2020: x=19220=9.6x = \frac{192}{20} = 9.6

Step 4: Find the measure of each angle

Now that we know x=9.6x = 9.6, substitute this value back into each angle expression:

  1. 13x4813x - 48^\circ: 13(9.6)48=124.848=76.813(9.6) - 48 = 124.8^\circ - 48 = 76.8^\circ

  2. 7x+367x + 36^\circ: 7(9.6)+36=67.2+36=103.27(9.6) + 36 = 67.2^\circ + 36 = 103.2^\circ

Final Answer:

  • The first angle is 76.876.8^\circ.
  • The second angle is 103.2103.2^\circ.

These two angles sum to 180180^\circ, confirming they are supplementary.
