The exterior angles, taken one at each vertex, always sum up to. Sum of three angles \alpha \beta, \gamma is equal to 180180\degree180, as they form a straight line. To determine the missing angle(s) in a triangle, you can call upon the following math theorems: Every set of three angles that add up to 180 can form a triangle. To do so, we need to start with at least three of these values, including at least one of the sides. Look at the equation carefully: 10 2 = | B C | 2 + 6 2. There are three possible cases: ASA, AAS, SSA. Start with the two known sides and use the famous formula developed by the Greek mathematician Pythagoras, which states that the sum of the squares of the sides is equal to the square of the length of the third side: As an example, finding the length of the third side for a triangle with two other sides length 5 and 12: From there you square . The inverse sine will produce a single result, but keep in mind that there may be two values for \(\beta\). $$c^2=(c+2)^2+25-2(c+2)\cdot 5\cos(\gamma)$$ The problem is to find the length AG.
