Answer:
Let the unknown equal angles be x
Third angle = 70°
=>x + x + 70° = 180°
[ Angle Sum Property of Triangle]
=>2x + 70° = 180°
=> 2x = 180° - 70°
=> 2x = 110°
=> x = 110/2
=> x = 55°
Therefore, both of the angles are of measure 55°
Hence the measures of angles in triangle are 55°, 55° & 70°
Hope it helped you...
