Question

Calculate the value of 0. Write your equation.

Answer 1

Answer:

θ = 67.4°

Step-by-step explanation:

using the SOHCAHTOA method,

Here opposite is 12 cm, hypotenuse is 13 cm, adjacent is 5 cm.

Using the formula:

$sin(\beta ) = \frac{oppsoite }{hypotenuse}$

$sin(\beta ) = \frac{12}{13}$

$\beta = sin^{-1}(\frac{12}{13} )$

β = 67.4°

Answer 2

Right angle triangle so apply trigonometric identies.

$\\ \tt\hookrightarrow cos\theta=\dfrac{5}{13}$

$\\ \tt\hookrightarrow cos\theta=0.37$

$\\ \tt\hookrightarrow \theta=cos^{-1}(0.37)$

$\\ \tt\hookrightarrow \theta=68.3$
