Answer» GivenAB=ACThusAngle C = angle B because angles opposite to equal sides are equal so angle C = 65°angle A = angle A + angle B + angle C= 180 ° angle sum property of triangle angle A+ 65° + 65° = 180°angle A = 180 - 130 angle A = 50°

Answer»

GivenAB=ACThusAngle C = angle B

because angles opposite to equal sides are equal

so angle C = 65°angle A = angle A + angle B + angle C= 180 °

angle sum property of triangle

angle A+ 65° + 65° = 180°angle A = 180 - 130 angle A = 50°
