## How do you find the missing side of a right triangle with one side and one angle?

How do you solve a right angle triangle with only one side?

- If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle.
- Alternatively, multiply the hypotenuse by cos(θ) to get the side adjacent to the angle.

## What is the adjacent side of angle A?

The adjacent side is the non-hypotenuse side that is next to a given angle.

**How do you find the side length of an angle?**

Key Takeaways

- The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.
- In a right triangle, one of the angles has a value of 90 degrees.
- The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.

**How do you know when to use SOH CAH and Toa?**

How do you know when to use SOH CAH and Toa? If in the question, the values of the hypotenuse and the opposite side (from θ) are provided, use soh i.e, Sin = Opposite / Hypotenuse. If you are working with the Adjacent side and the Hypotenuse, use CAH i.e, Cos = Adjacent / Hypotenuse.

### What is Sohcahtoa in trigonometry?

Sohcahtoa is simply anything that is used to remember the definition of Trigonometric Ratios (i.e. sine, cosine and tangent) easily. The meaning for the word can also be understood by breaking it into parts = SOH CAH TOA. SOH denotes the identity for sine, where, Sin = Opposite / Hypotenuse Like wise, CAH denotes, Cos = Adjacent / Hypotenuse

### Is SOH-CAH-TOA also used for left triangles?

No, Soh-Cah-Toa is only applicable for the right triangle (triangle with 90°). As trigonometry is basically made for right-angled triangles, thus the use of soh, cah, and toa is also used for only right triangles.

**When to use Sohcahtoa?**

Q: When to use sohcahtoa? A: When you are given a right triangle, where two of the side lengths are given and you are asked to find the third side. Q: Where is the hypotenuse of a right triangle? A: They hypotenuse of a right triangle is always opposite the 90 degree angle, and is the longest side.
