Hello!
First, let's analyze the figure and write each side:
Analyzing it, we don't have enough information yet to calculate the tangent (because we don't know the measurement of P).
So, let's calculate the opposite side (by Pithagoras):
As we know the opposite side, we can calculate the tangent of P, look:
Curiosity: using the trigonometric table, this value corresponds to approximately 13º.
Answer:
The tangent of P is 0.225.
