# Do I use SOH CAH or Toa?

## Do I use SOH CAH or Toa?

We can use SOHCAHTOA to find a missing side of a right angled triangle when we have another side and a given angle. We can use SOHCAHTOA to find a missing angle of a right angled triangle when we have two given sides. If we have two sides and we want to find the third we can use the Pythagorean Theorem a2+b2=c2 .

How do you find the missing sides and angles of a right triangle using trigonometry?

How to find the sides of a right triangle

1. if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² – b²)
2. if leg b is unknown, then. b = √(c² – a²)
3. for hypotenuse c missing, the formula is. c = √(a² + b²)

What is Sohcahtoa and how to use the trig ratios?

What is SOHCAHTOA and how to use the trig ratios to find missing sides and missing angles on right triangles? The following diagram shows the SOHCAHTOA formula for sin, cos, and tan. Scroll down the page for more examples and solutions on SOHCAHTOA. What is SOH-CAH-TOA? SOHCAHTOA is a mnemonic to help us remember the trigonometric ratios.

### What is SOH CAH TOA?

SOH CAH TOA – trigonometry. A way to remember the definitions of the three most common trigonometry functions: sin, cos and tan. Used as a memory aid for the definitions of the three common trigonometry functions sine, cosine and tangent . When spoken it is usually pronounced a bit like “soaka towa”.

How to remember trigonometric ratios?

Remember the three basic ratios are called Sine, Cosine, and Tangent, and they represent the foundational Trigonometric Ratios, after the Greek word for triangle measurement. And these trigonometric ratios allow us to find missing sides of a right triangle, as well as missing angles. How To Remember Trig Functions?

What is sin in trigonometry?

It’s a mnemonic device to help you remember the three basic trig ratios used to solve for missing sides and angles in a right triangle. It’s defined as: SOH: Sin(θ) = Opposite / Hypotenuse; CAH: Cos(θ) = Adjacent / Hypotenuse; TOA: Tan(θ) = Opposite / Adjacent
