Are you ready to jump into the fun world of trigonometry?

Let's learn how to use trigonometric ratios to find the missing sides of right triangles!

It's all about understanding how the angles and sides are connected. So, let’s get started!

Step 1: Identify the Sides

In a right triangle, there are three sides:

• Hypotenuse: This is the longest side, and it's across from the right angle.

• Adjacent Side: This side is next to the angle you are studying.

• Opposite Side: This side is across from the angle you are looking at.

Step 2: Use the Right Ratios

There are three main trigonometric ratios:

• Sine (sin): This ratio is calculated using: $\sin(\theta) = \frac{\text{Opposite}}{\text{Hypotenuse}}$

• Cosine (cos): Here is the formula: $\cos(\theta) = \frac{\text{Adjacent}}{\text{Hypotenuse}}$

• Tangent (tan): And this formula is: $\tan(\theta) = \frac{\text{Opposite}}{\text{Adjacent}}$

Step 3: Setting Up the Equations

To find a missing side, choose the right trigonometric ratio based on the angle you know and the sides you need:

• If you know the angle and the hypotenuse, use sine or cosine.

• If you know the angle and one of the sides, use tangent.

Step 4: Solve the Problem

Rewrite the equation based on what side you want to find.

And just like that! You can discover the missing side of your triangle.
