WebSolution: Since I is the incenter of the triangle, the segments connecting the incenter to the vertices are bisectors, so they divide the angles into two equal parts. This means that the three interior angles of the triangle are: 2×35°=70° 2×31°=62° 2× x =2 x A triangle always has a sum of interior angles equal to 180°, so we have:
