What is the value of $$\text{sin}(90°)$$ ?

The value of $$\text{sin}(90°)$$ is 1.

What is the value of $$\text{cos}(0°)$$ ?

The value of $$\text{cos}(0°)$$ is 1.

What is the formula for the area of a triangle?

The area of a triangle can be calculated using the formula: $$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$$ .

What is the definition of a radian?

A radian is a unit of angular measure defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.

What is the sine rule in trigonometry?

The sine rule states that in any triangle, the ratio of the length of a side to the sine of its opposite angle is constant: $$\frac{a}{\text{sin}(A)} = \frac{b}{\text{sin}(B)} = \frac{c}{\text{sin}(C)}$$ .

What is the cosine rule in trigonometry?

The cosine rule relates the lengths of the sides of a triangle to the cosine of one of its angles: $$c^2 = a^2 + b^2 - 2ab \times \text{cos}(C)$$ .

How do you find the length of a side in a right triangle using trigonometric ratios?

To find the length of a side, use the appropriate trigonometric ratio: $$\text{sin}(θ) = \frac{\text{opposite}}{\text{hypotenuse}}$$ , $$\text{cos}(θ) = \frac{\text{adjacent}}{\text{hypotenuse}}$$ , or $$\text{tan}(θ) = \frac{\text{opposite}}{\text{adjacent}}$$ .

What is the value of $$\text{tan}(45°)$$ ?

The value of $$\text{tan}(45°)$$ is 1.
