In geometry vertical angles are congruent, meaning they have the same degree measure. You see these when two straight lines form and X shape. Angles that are opposite one another are called vertical angles. If two of these congruent angles have the same degree measure and Angle 1 is (3x + 10) degrees and Angle 2 is (5x - 4) degrees, set the
expressions equal to one another and find the degree measure. Hint: Don't just solve for the variable X, you have to solve for degree measure by substitution. Do so in both
expressions as a way to check your work. The degree measures should be the same if you solved for the variable correctly.
