Question

triangle ABC is an isosceles triangle in which AB equal to AC and LM is parallel to BC if angle A is equal to 60 find angle lmc ​

Answer 1

answer

abc is a isosceles triangle in which two sides are equal

given ab=ac

a=60degree

Lm parallel to bc

so we know a+b+c=180

a=60+b+c=180

60+2x=180

2x=180-60

2x=120

x=120/2

x=60

a=60,b=60,c=60
