Let the ∠2, ∠3 and ∠4 be x
Sum of angles on a straight line = ∠5 + ∠4
150° + x = 180°
x = 30°
Sum of angles on a straight line = ∠1 + ∠2 + ∠3
∠1 + x + x = 180°
∠1 + 2x = 180°
∠1 + 2 × 30° = 180°
∠1 + 60° = 180°
∠1 = 120°

The lines L1 and L2 are parallel lines cut by a transversal. If the measure of one of the corresponding angles is 75°, then what is the measure of the other corresponding angle?
Let AB and CD be two parallel lines and PQ be a transversal such that PQ intersects AB at the point R and CD at the point S, respectively. If ∠BRP = (2x + 13)° and ∠DSP = (3x − 22)°, then find ∠CSP.
