Math >. … WebThe equilateral triangle can be split into two right-angled triangles. The length of the third side of the triangle can be calculated using Pythagoras' theorem. \[c^2 = a^2 + b^2\] \[2^2 = a^2 + 1^2\] WebThis law is applicable where two sides of a triangle and the angle opposite one of them are given. In such a case, the angle opposite the other side of the triangle can be calculated using law of sines. The law specifies that the sum of the interior angles of a triangle must equal to 180 degrees. The third angle can easily be determined then. trans dr swiner durham family medicine

WebSolution: By using the triangle inequality theorem, we can say that the length of the third side must be less than the sum of the other two sides. So, the third side is less than 8 units + 2 units = 10 units. Also, the third side cannot be less than the difference between the other two sides. So, the third side is greater than 8 units - 2 units ... WebWhere a and b are two sides of a triangle, and c is the hypotenuse, the Pythagorean theorem can be written as: a 2 + b 2 = c 2 EX: Given a = 3, c = 5, find b: 3 2 + b 2 = 5 2 9 + b 2 = 25 b …

WebThe sine rule (or the law of sines) is a relationship between the size of an angle in a triangle and the opposite side.
