In the triangle, cos A = 8/17. Find Sin A
15/17
8/15
17/15
15/8

15/17

Step-by-step explanation:

Cos A = 8/17

Recall that cos = adjacent/hypotenuse

Since the hypotenuse is 17 and the adjacent is 8, the value of the opposite which is the remaining side of the triangle will be:

Let the side be x

x² = 17² - 8²

x² = 289 - 64

x² = 225

x = ✓225

x = 15

The remaining side has a value of 15

Recall that sin = opposite/hypotenuse

Sin A = 15/17
