how do you find the side of a triangle with two sides and one angle If you know two other sides of the right triangle it s the easiest option all you need to do is apply the Pythagorean theorem a b c If leg a is the missing side then transform the equation to the form where a is on one side and take a square root a c b If leg b is unknown then b c a
Use your calculator Type in 39 and then use the sin key That s easy sin 39 0 6293 So now we have 0 6293 d 30 Now we rearrange it a little bit and solve Start with 0 6293 d 30 Swap sides d 30 0 6293 Calculate the length of side X in the right triangle below How to find the side length of a right triangle sohcahtoa vs Pythagorean Theorem Video tutorial practice problems and diagrams

Upvote Downvote Flag David Calkins 8 years ago You can ONLY use the Pythagorean Theorem when dealing with a right triangle The law of cosines allows us to find angle or side length measurements for triangles other than right triangles The third side in the example given would ONLY 15 if the angle between the two sides was 90 degrees Such a triangle can be solved by using Angles of a Triangle to find the other angle and The Law of Sines to find each of the other two sides See Solving AAS Triangles 3 ASA This means we are given two angles of a triangle and one side which is the side adjacent to the two given angles
Solution To find The sides of a right triangular park Given Hypotenuse 10 in The base angle 30 degrees Using sides of a triangle Formula sin Length of opposite side Length of Hypotenuse side sin 30 x 10 Assuming Length of opposite side x 1 2 x 10 x 5 in In a right triangle the base and the height are the two sides that form the right angle Since multiplying these two values together would give the area of the corresponding rectangle and the triangle is half of that the formula is area base height

The formula is b 2acos alpha b 2acos where a and b are the lengths of the sides of the triangle and is the angle between sides a and b You can rearrange the formula to solve for side a The formula becomes a dfrac b 2cos alpha a 2cos b Right triangle through sides Intro to the Pythagorean theorem Pythagorean theorem example Pythagorean theorem intro problems Pythagorean theorem with isosceles triangle Use Pythagorean theorem to find right triangle side lengths Use Pythagorean theorem to find isosceles triangle side lengths Right triangle side lengths
Trigonometry can be used to find the length of a side in a triangle How to calculate the length of a side For a right angled triangle follow these steps to calculate the length of a side Tan A opposite adjacent A B C length A S O H C A H T O A Step 2 Create an equation using the trig ratio sine and solve for the unknown side sin B opposite hypotenuse Define sine sin 50 A C 6 Substitute 6 sin 50 A C Multiply both sides by 6 4 60 A C Evaluate with a calculator I m confused
