Question

In triangle ABC with the right triangle at vertex C, sin a=35/7

Answer 1

In the figure, the value of sine b is

√(14) / 7

How to find sin b

To find sine b, we use angle a as follows

We need to find the distance AC

AC = √(7² - (√35)²)

AC = √(14)

Solving for sine b

sine b = AC / 7

sine b = √(14) / 7
