Sum of all three angles in a triangle = 180 . So, one is 70 degree then 180-70=110 . 110/2 =55 degree . Therefore 2 sides are 110and 55 degree .
The sum of all the angles in a traingle is 180°. Let the two angles be 2x, then 70°+ x+ x= 180° 2x= 180°-70° [ Transposition method] 2x= 110° X= 55° Hence, the measure of the other two angles is 55°.
