How do you find the angle using the sine function?

To find the angle using the sine function, you can use the inverse sine function: $$\theta = \text{sin}^{-1}igg(\frac{\text{opposite}}{\text{hypotenuse}}igg)$$ .

How do you find the angle using the cosine function?

To find the angle using the cosine function, you can use the inverse cosine function: $$\theta = \text{cos}^{-1}igg(\frac{\text{adjacent}}{\text{hypotenuse}}igg)$$ .

How do you find the angle using the tangent function?

To find the angle using the tangent function, you can use the inverse tangent function: $$\theta = \text{tan}^{-1}igg(\frac{\text{opposite}}{\text{adjacent}}igg)$$ .

What is the formula for the diagonal of a rectangle?

The diagonal (d) of a rectangle can be found using the Pythagorean Theorem: $$d = \text{sqrt}(l^2 + w^2)$$ , where l is the length and w is the width.

What is the value of $$\text{sin}(30^\text{o})$$ ?

The value of $$\text{sin}(30^\text{o})$$ is $$\frac{1}{2}$$ .
