Given:
figure l is parallel to m and t is the transversal
Concept Used:
The sum of the angles formed between two parallel lines is 180 degrees.
Vertically opposite angles are equal.
Solution:
The sum of the angles formed between two parallel lines is 180 degrees.
120-a = 180°
a= 60°
Vertically opposite angles are equal
a = x
x = 60°
Thus, correct option is (c)

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.
