To solve this problem, you will first use the Angle Sum Property to determine the value of <em>x </em>after creating an algebraic equation, combining like terms, and subtracting from both sides of an equation.
<h3>Use the Angle Sum Property</h3>The Angle Sum Property states that all interior angles of a triangle will summate to 180º.
An equation can be created to find this when you are given two angles and missing a third. That third angle can be referred to as <em>x</em> in this scenario.
Adding the two known angles and the unknown angle will result in a sum of 180º. This means that our unknown is <em>x</em> and can therefore be placed in an equation:
Combine the like terms by combining the constants on the left side of the equation using addition:
After combining like terms, subtract 107 from both sides of the equation:
The final answer is <em>x</em> = 73 degrees.
