3. Right Triangles and Trigonometric Ratios
Sign In
Use the Pythagorean Theorem. Then use the trigonometric ratios.
G
We will compare the given expression with this definition. tan θ = Opposite/Adjacent ⇒ tan X = 8/15 Next, we can assume that the length of the opposite side to X is 8 and the length of the adjacent is 15.
Substitute values
Calculate power
Add terms
sqrt(LHS)=sqrt(RHS)
Then, we can rewrite the trigonometric ratio for sine by using these values. sin θ = Opposite/Hypotenuse ⇒ sin Y = 15/17 Therefore, the correct option is G.
