Question

what is sin a?
25
4√6
23
sin a = ?

Explanation:

Step1: Recall the definition of sine in a right - triangle

In a right - triangle, \(\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}\). For angle \(A\), the side opposite to angle \(A\) is \(23\), and the hypotenuse is \(25\).

Step2: Apply the formula

\(\sin A=\frac{23}{25}\)

Answer:

\(\frac{23}{25}\)
