Question

If sin 49° is approximately 3/4, which is closest to the length of the of NO ?

Options
25 m
66 m
75 m
80 m

Answer 1

75 meters.

Explanation:

In this case, you are trying to find side length NO. In accordance to SOH CAH TOA, you can use a sine function to find the missing side length, since you are given the hypotenuse.

sin(49) = x / 100

x = sin(49) * 100

x = 0.7547095802 * 100

x = 75.47095802

So, the closest answer would be 75 meters.

Hope this helps!
