The adjacent and opposite can only be found if you choose one of the non right angled angles. No two angles can total to 180 degrees or more. Uses law of sines to determine unknown sides then Heron's formula and trigonometric functions to calculate area and other properties of a given triangle. Entering sides of values 1.00, 2.00, and 2.00 will yield much more acurate results of 75.5, 75.5, and 29.0. Also the side can be found by perimeter or area. Use a calculator, spreadsheet, or another tool to solve for the unknown sides of the given right triangle. SSA ' is when we know two sides and an angle that is not the angle between the sides. Let a, b and c be the three sides of a РћвЂќABC and c is the largest side. use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180Р’В° to find the last angle. Area of a parallelogram given base and height. ' There can be two answers either side of 90Р’В° (example: 95Р’В° and 85Р’В°), but a calculator will only give you the smaller one. AAS - a side, 1 adjacent angle, and the opposite angleРІР‚В¦ Top Angle Base Angles 30Р’В° Height 3' Area 15.59 ftР’Р†. The third side a is said to be opposite to РћС‘. Step 4 Find the angle from your calculator using tan-1. Calculator solve triangle specified by all three sides (SSS congruence law). Enter the three side lengths and press 'Calculate'. If you know that triangle is an equilateral triangle, isosceles or right triangle use specialized calculator for it calculation. Calculates the three angles and area of a triangle given three sides. Depending on the figures you know this rhombus calculator can perform the following calculations: If Angle (A) is given then the other 3 angles will be computed: B = 180Р’В° - A.
