For this figure what is the value of x? ____° (I will put the image down below!)

OpenStudy (mathstudent55):

The two angles marked x have the same measure because they are vertical angles. |dw:1446573266138:dw|

OpenStudy (anonymous):

so it would be 66° ?

OpenStudy (mathstudent55):

Correct. Since the measures of angles of the left triangle add to 180, and the missing angle is 66, then x is also 66. Good job!
