Math Problem Statement

Given two angles, one is 112° and the other is (3x + 11)°, forming a linear pair. Find the value of x.

Solution

The image shows two angles with values: 112112^\circ and (3x+11)(3x + 11)^\circ, along with red arrows indicating that these angles may be adjacent. Given the appearance, these angles likely form a linear pair, meaning they add up to 180180^\circ.

To solve for xx:

  1. Since the angles form a linear pair, their sum is 180180^\circ. So, 112+(3x+11)=180112^\circ + (3x + 11)^\circ = 180^\circ

  2. Simplify the equation: 112+3x+11=180112 + 3x + 11 = 180 123+3x=180123 + 3x = 180

  3. Subtract 123 from both sides: 3x=1801233x = 180 - 123 3x=573x = 57

  4. Divide both sides by 3: x=573x = \frac{57}{3} x=19x = 19

Thus, the value of xx is 19.
