Hewo! Thanks for the question.
So, we have given a right angle triangle with adjacent side = 16 and let 74Β° is angle A, We have to find the perpendicular or x.
Let's move straight to the answering process,
According to question,
Tan74Β° = opp/adj
Tan74Β° = x/16
x = Tan74Β°Γ16
Tan74Β° is equals to 3.48,
x = 3.48Γ16
x = 55.8
Hope it helps!<3
