Share with your friends Share 0 OLD Radhika Gupta answered this Dear Student, Solution: Let ∠A,∠B and ∠C are the three angles of a triangle,Sum of the three angles in a triangle=180°⇒∠A+∠B +∠C=180°⇒130°+∠B +∠C=180° (Since one angle is given)⇒∠B +∠C=180°-130°=50°Now,∠B +∠C2=25°After bisecting the sum of the anglesTherefore, Required angle = 180°-25°=155° Regards 0 View Full Answer
