Answer:

∠MON = 57°

Step-by-step explanation:

Given that OL and ON are perpendicular lines then ∠LON = 90° and

∠LOM + ∠MON = 90, substitute values

3x - 15 + 5x - 23 = 90, that is

8x - 38 = 90 ( add 38 to both sides )

8x = 128 ( divide both sides by 8 )

x = 16

Hence

∠MON = 5x - 23 = (5 × 16) - 23 = 80 - 23 = 57°
