Question

find: tan a
answer
72/54 54/90 72/90 54/72

Explanation:

Step1: Recall the tangent formula

In a right - triangle, \(\tan\theta=\frac{\text{opposite}}{\text{adjacent}}\). For angle \(A\), the opposite side is \(BC = 72\) and the adjacent side is \(AC=54\).

Step2: Apply the formula

\(\tan A=\frac{\text{opposite}}{\text{adjacent}}=\frac{72}{54}\)

Answer:

\(\frac{72}{54}\)
