In the given triangle, 
and 
has a measure of 
. What is the value of x ?
ExplanationShow
Choice B is correct. Since , the measures of their corresponding angles, and 
, are equal. Since has a measure of , the measure of is also . Since the sum of the measures of the interior angles in a triangle is 
, it follows that 
, or 
. Subtracting by 134 on both sides of this equation yields 
.
Choices A, C, and D are incorrect and may result from calculation errors.
