Answer:
According to the "Triangle TheOrem", a triangles interior angles are always a 180°.
Therefore, to find the last remaining angle of the triangle, you will have to find the measure of the bottom angles (65° + 65° = 130°) THEN subtract 180° by 130°
65° + 65° = 130° (measures of the two bottom angles)
180° - 130° (to find the remaining angle!) = 50°
ANSWER = 50°
