To Solve for missing angle measures using algebra
Step 1: Figure out if the angles given are congrsuaemnet, supplementary (180) or complementary(90) Step 2: Set up an equation that relates the angles
If congruent set the measures equal
If complementary
add the measures & set them equal to
90
Step 3: Then solve for x Step 4: Find missing angle measures
If supplementary
add the measures & set them equal to
180
