What is the measure of ∠ADC in the figure below?

The angles make a straight line which adds up to how many degrees?

Step 1 - Add the angle measurements together and make them equal to the number of degrees in a straight line

Step 2 - Combine like terms

Step 3 - What do we have to subtract from both sides of the equation?

Step 4 - What do we have to divide both sides of the equation by?

Step 5 - Plug that number in to the expression located at ∠ADC to find your answer

Quadrilateral A B C D. Side A D is extended beyond vertex D. Point E is on this extension. Side C D is extended beyond vertex D. Point F is on this extension. Angle A D F is labeled open parenthesis 2 X plus 3 close parenthesis degrees. Angle A D C is labeled open parenthesis X plus 3 close parenthesis degrees.
