Answer:
Option B is the right choice,congruent to are
.
Step-by-step explanation:
If we look on to the diagram and the options we can sort out the angles on the basis of our requirement.
There are three sets arising from the angles.
[Corresponding angles]
The corresponding angles are the ones at the same location at each intersection.
[Vertically opposite angles]
And
[Alternate interior angles]
Now
[Corresponding angles]
[Vertically opposite angles]
[Vertically opposite angles]
So the correct pair from the options given is B which includes

Take the derivative with respect to t
the maximum and minimum values occur when the tangent line is zero so we set the derivative to zero
divide by w
we add sin(wt) to both sides
divide both sides by cos(wt)
OR
(wt)=2(n*pi-arctan(2^0.5))
(wt)=2(n*pi+arctan(2^-0.5))
where n is an integer
the absolute max and min will be
since 2npi is just the period of cos
substituting our second soultion we get
since 2npi is the period
so the maximum value =
minimum value =
