Question

cm. Find the area of triangle in the given figure AB = AC and BC extended to the point D. Find y-X A 2x B D​

Answer 1

Answer:

here in the question

since ABC is a triangle so

2x+2x+x=180

x=36

now by exterior angle theorem

angleABC +angleBAC=angleACD

so 2x+ x= y

now x=36 so putting this value we get

72+x=y,

from here y-x=72

hope you will get it
