Delve into the essence of trigonometric ratios, comprehending their significance in defining relationships between angles and sides of right triangles. Discover the intricacies of calculating sine, cosine, and tangent ratios, unraveling their applications in diverse fields.

## Trigonometric Ratios

Trigonometric ratios are functions that relate the lengths of sides in a right triangle to the angles of the triangle. The three main trigonometric ratios are sine, cosine, and tangent.

### Sine

The sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

sin(θ) = opposite/hypotenuse

### Cosine

The cosine of an angle is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.

cos(θ) = adjacent/hypotenuse

### Tangent, Trigonometric ratios and finding missing sides worksheet answers

The tangent of an angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

tan(θ) = opposite/adjacent

## Finding Missing Sides

Trigonometric ratios can be used to find missing sides in right triangles. The steps for using trigonometric ratios to find missing sides are as follows:

### Sine

- Identify the angle opposite the missing side.
- Use the sine ratio to set up an equation.
- Solve the equation for the missing side.

### Cosine

- Identify the angle adjacent to the missing side.
- Use the cosine ratio to set up an equation.
- Solve the equation for the missing side.

### Tangent, Trigonometric ratios and finding missing sides worksheet answers

- Identify the angle opposite the missing side.
- Use the tangent ratio to set up an equation.
- Solve the equation for the missing side.
