Question

If 15 sin theta = 8 . then find value of cos theta and tan theta​

Answer 1

Step-by-step explanation:

this is known as triangle method

Answer 2

The value of cos θ and tan θ is 0.845 and 0.630.

Explanation:

Given: 15 sin θ = 8, cos θ and tan θ = ?

sin θ = $\frac{8}{15}$

According to the Pythagoras theorem, sin θ = $\frac{opposite}{hypotense}$, cos θ = $\frac{adjacent side}{hypotenuse}$, tan θ = $\frac{opposite}{adjacent}$

Applying the Pythagoras theorem, h² = a² + b²

⇒ 15² = a² + 8²

⇒ a² = 15² - 8²

⇒ a² = 161

a = 12.68 (adjacent side)

Cos θ = $\frac{12.68}{15}$

Cos θ = 0.845

Tan θ = $\frac{8}{12.68}$

Tan θ = 0.630
