Question

In triangle ABC, AB=AC and side BC is produced to point D, such that angle ACD=150, then write the measure
of ABC​

Answer 1

Answer:

75degree

Step-by-step explanation:

we know that sum of all angles of a triangle is 180 degree so..

angle abc=180degree

if angle acd=150degree

then angle acd+angle acb=180 degree

150+acb=180

acb=180-150=30 degree

then

angle abc=angle a + angle b + angle c= 180 degree

a+b+30=180

let a and b be x

x+x+30=180

2x+30=180

2x=180-30=150

2x=150

x=150÷2=75degree

therefore angle a and b are 75 degree so

angle abc=75 degree:- ANSWER
