Trigonometry how to find angle with 2 sides
We can find an unknown angle in a right-angled triangle, as long as we know the lengths of two of its sides. The answer is to use Sine, Cosine or Tangent! But which one to use? We have a special phrase "SOHCAHTOA" to help us, and we use it like this: 1. Adjacentis adjacent to the angle, 2. Oppositeis opposite … See more These are the four steps we need to follow: 1. Step 1Find which two sides we know – out of Opposite, Adjacent and Hypotenuse. 2. Step 2 Use SOHCAHTOA to decide which one of Sine, Cosine orTangent to use in … See more Let’s look at a couple more examples: Unless you’re told otherwise, angles are usually rounded to one place of decimals.
