Which diagram shows lines that must be parallel lines cut by a transversal

see the attached figure with letter to better understand the problem

we know that

if the lines r and s are parallel

then

m∠c=m∠> by corresponding angles

therefore

the answer in the attached figure

This graph is nonlinear

The initial displacement of the weight is 40cm

The weight first returns to equilibrium when t=1/2

Step-by-step explanation:

thats the answer i only had time to give not to explain
