Question

In trianglc ABC, AB = AC and angle B = 40°
then find the values of other two angles.​

Answer 1

Answer:

AB = AC

so angleB=angleC. {ABC is isosceles and base angles of isosceles triangle are equal}

C=B=40°

A+B+C=180°{angle sum property}

A+40+40=180°

A=100°

Step-by-step explanation:

A=100°

B=40°

C=40°

Answer 2

Answer:

In triangle ABC, AB=AC

so it is an isosceles triangle

angleB=40°

so,angle C=40°

sum of the three angles of a triangle is 180°

so, angle A={180-(40+40)} °=(180-80)°=100°
