Finding a side of a triangle
WebJun 26, 2024 · Answer: If you know two angles, then you can work out the third since all the angles sum to 180 degrees. If the sides are a, b and the hypotenuse is c (opposite angle A), and the angles are A, B and C, then Sin A = a/c, so a … WebFeb 3, 2024 · If you know that the area of a triangle is 20, and one side is 4, then: A = 20 and b = 4. 3 Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle! Example 20 = 1/2 (4)h Plug the numbers into the equation.

WebTo find the area of a right triangle we only need to know the length of the two legs. We don’t need the hypotenuse at all. That’s because the legs determine the base and the height of the triangle in every right triangle. So we use the general triangle area formula (A = base • height/2) and substitute a and b for base and height. WebMay 4, 2024 · The hypotenuse is the side of the triangle opposite the right angle. For right triangles only, enter any two values to find the third. See the solution with steps using …

Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c.
