Question

in the triangle shown, what is the value of sin y°?
a
b
c
d

Explanation:

Step1: Recall the sine formula

In a right - triangle, \(\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}\).

Step2: Identify the sides relative to angle \(y\)

For angle \(y\), the opposite side is \(5\) and the hypotenuse is \(86\).
So, \(\sin y=\frac{5}{86}\)

Answer:

D. \(\frac{5}{86}\)
