Given three sides find angle
WebExample 2:If the three sides of a triangle are 4 units, 6 units, and 8 units, respectively, find the area of the triangle. Solution: In order to find the area of a triangle with 3 sides given, we use the formula: A =√[s(s-a)(s-b)(s-c)] The sides of the given triangle are 4 units, 6 units, and 8 units. The semi-perimeter of the triangle is, WebThe 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. In the example in the video, the angle between the two sides is NOT 90 degrees; it's 87. As such, that opposite side length isn ...
