Answer:
Botn are correct
Step-by-step explanation:
Tan ratio can be obtained by opposite/adjacent
Both students are correct. They have different values only because they have taken different reference angles
Rhianna has taken angle A as the reference angle,
So tanA = opposite/adjacent = BC/AB
tanA = 3/4
Christopher has taken angle C as the reference angle,
So tanC = opposite/adjacent = AB/BC
tanC = 4/3
