Three angles have measures that add to 180° . The angles have the following measures: m∠KLM=(x+30)°, m∠MLN=60°, and m∠NLP=(2x)°. What is an equation to solve for the unknown angle measures? Write the equation in simplest terms.
To solve for the unknown angle measures, we can add up the measures of the three angles and set it equal to 180°.
m∠KLM + m∠MLN + m∠NLP = 180°
(x + 30°) + 60° + (2x)° = 180°
Thus, the equation to solve for the unknown angle measures is:
x + 30 + 60 + 2x = 180
