how to find the opposite side of a right angle triangle These are the four steps to follow Step 1 Find the names of the two sides we are using one we are trying to find and one we already know out of Opposite Adjacent and Hypotenuse Step 2 Use SOHCAHTOA to decide which one of Sine Cosine or Tangent to use in this question
In a right triangle the hypotenuse is the side opposite of the right angle In this case the right angle is formed by sides and leaving as the hypotenuse In a right triangle the hypotenuse is the longest side an opposite side is the one across from a given angle and an adjacent side is next to a given angle We use special words to describe the sides of right triangles

For a right angled triangle follow these steps to calculate the length of a side x when another side and an angle is given Label the two sides that contain information in Step 1 Find which two sides we know out of Opposite Adjacent and Hypotenuse Step 2 Use SOHCAHTOA to decide which one of Sine Cosine or Tangent to use in this question Step 3 For Sine calculate Opposite Hypotenuse for Cosine calculate Adjacent Hypotenuse or for Tangent calculate Opposite Adjacent
The first part of this video will explain the difference between the hypotenuse adjacent and opposite sides of a right triangle Then it shows how to use the sine formula the SOH formula Omni s triangle side calculator allows you to calculate the length of the sides of a triangle Continue reading to find out how to calculate the sides of a triangle for three different cases If two sides and one angle are known If two angles and one side are known and If two sides and the perimeter are known

Sal is given a right triangle with an acute angle of 65 and a leg of 5 units and he uses trigonometry to find the two missing sides Created by Sal Khan and Monterey Institute for Technology and Education A hypotenuse is the longest side of a right triangle It s the side that is opposite to the right angle 90 Hypotenuse length may be found for example from the Pythagorean theorem You can learn more about this in
In this formula is an angle of a right triangle the opposite is the length of the side opposite the angle and the adjacent is the length of side next to the angle The image below shows what we mean How to Use the Tangent Function to Find the Opposite of a Right Triangle Finding the opposite side of a right triangle is easy when we know the angle and the hypotenuse Question What is the length of the opposite side of the right triangle shown below Step by Step 1 Start with the formula Opposite sin hypotenuse 2 Substitute the angle and the length of the hypotenuse into the formula
