Find x and y. Give reasons to justify your solution.

AB, CD , and EF are straight lines.

x = 15.6°, y = 14°

Step-by-step explanation:

From the picture we can see that:

∠COE and ∠DOF are vertical angles as formed by intersection of lines CD and EF, so these angles are equalMO⊥AB as ∠MOB = 90°, therefore ∠AOM = 90°

Considering the above we get below to find x:

12° + 2x + 3x = 90°5x = 90° - 12°5x = 78°x = 78°/5x = 15.6°

And using this to find y:

48° + 3y = 90°3y = 90 - 483y = 42°y = 42°/3y = 14°
