Question

in triangle abc if, AB=AC and angle B=65° find angleA​

Answer 1

Hey mate!!
Ur answer!!
=If AB and AC are equal then the triangle is an isosceles triangle.So,the base angles of an isosceles triangle are always equal.So,
Angle A+Angle B+Angle B=180 degrees
Angle A+Angle 2B=180 degrees
Angle A+2x65=180 degrees
Angle A=180-130 degrees
Angle A=50 degrees
