Idk you should look it up on google and see if that would help you !!
The general form of such an equation will be

where
A = amplitude (3)
B = horizontal shift to the right (-π)
C = period (4π)
D = vertical offset (0)
Your equation will be ...
9514 1404 393
Answer:
yes
Step-by-step explanation:
There are at least a couple of ways to show congruence.
1. ∠P ≅ ∠Q . . . given; PB ≅ QB . . . given; ∠QBS ≅ ∠PBR . . . vertical angles; ΔPRB ≅ ΔQSB by ASA
