Question

in a triangle if angle a + angle b equals to 140 degree and will be angle c is equal to 120 degree find the measure of angle b










please help.... will mark as a brainlist​

Answer 1

this question is not right bcoz

the sum of every angle ( a+b+c) is equal to 180

when. here in this question

a+b=140&

c=120

then the sum of

a+b+c=140+120=260

which is not accurate

the sum of

a+b+c always equal to 180 of a triangle
