Angle LOM and angle MON are complementary angles. If m∠LOM = (x + 15)° and m∠MON = 48°, which equation could be used to solve for x?

1 answer

Since angle LOM and angle MON are complementary angles, their measures sum up to 90 degrees. So, the equation that can be used to solve for x is:

(x + 15) + 48 = 90
