I need help with sub and comp angles

Question

Question 6 (1 point) Find x if x and 2x are complementary. x = º Blank 1: Question 7 (1 point) Find x if 2x is the measure of an angle that is vertical to an angle that is 68º. x = º Blank 1:

Answer 1

Question 6: If x and 2x are complementary, then they represent angles that add up to 90 degrees.

x + 2x = 90. 3x = 90 x=30 degrees

one angle is 30 degrees, the other is 2(30) = 60 degrees.

Question 7:

If 2x is vertical to a 68 degree angle, then they are equal to each other. All vertical angles are congruent.

2x = 68. Therefore, x=34 degrees.
