What is the measure of the angle marked in blue in the attached picture? Hint: The 96 angle and the blue-marked angle form a linear pair? @Megan_xoxo

OpenStudy (anonymous):

84? right?

Directrix (directrix):

@Megan_xoxo Correct. Hold on for one more question.

Directrix (directrix):

@Megan_xoxo Hint: The red-marked angle and the 35 angle are known as Vertical Angles. Does that help? We are one step away from wrapping this up. :)

Directrix (directrix):

Theorem: Vertical angles are congruent. So, the red-marked angle has measure ? @Megan_xoxo

OpenStudy (anonymous):

96? correct?

Directrix (directrix):

The red marked angle is 35. It is congruent to the 35 angle that is vertical with it. ------ Here comes your last question. Solve the equation on the attachment for x. Recall that the sum of the interior angles of a triangle is 180. The value of x will be our answer.

OpenStudy (anonymous):

\[x=180-(180-96)-35=61{}^{\circ} \]
