in a geometric diagram, angle 1 and angle 2 are complementary, and they form a straight line with angle 3. if angle 1 = x, angle 2 = (2x), and angle 3 = 90, what is the measure of angle 2
Since angle 1 and angle 2 are complementary, we have:
angle 1 + angle 2 = 90
x + 2x = 90
3x = 90
x = 30
Therefore, angle 2 = 2x = 2(30) = 60
So, the measure of angle 2 is 60 degrees.
