Question

Use the diagram to find the following measures

A) triangle angle sum equation
B) value of x = ———- degrees

Answer 1

x = 71°

Explanation:

The sum of interior angles in a triangle is equal to 180°.

The measure of two angles out of three is given, we will use the following equation to find the value of the missing angle:

82 + 27 + x = 180 add like terms

109 + x = 180 subtract 109 from both sides

x = 71
