In rst cos r = 3/5 what is sin t

Answer 1

sin 4/9 if cos is 3/5

Explanation:

A cosine function is equivalent to the adjacent side divided by the hypotenuse , from SOH-CAH-TOA.

So, our adjacent side can be 3 , and the hypotenuse can be 5.

Then, we can use the Pythagorean theorem (a^2 + b^2 = c^2) to find the missing side length.

3^2+b^2=5^2

9+b^2 =25

b^2=16

b = 4

We found our three sides: 4, 5, and 9.

We know from SOH-CAH-TOA that the sine function is equivalent to the opposite side length divided by the hypotenuse length. So:

sin θ = 4/9
