Question

its urgent please answer to this question​

Answer 1

Answer:

x=70

Step-by-step explanation:

sum three angles of a triangle =180degrees

angle BAC=40degrees

angleABC=angle BCA

therefore sum of angles BCA and ABC be 2x

<BAC+<ABC+BCA=180

40+2x=180

2x=180-40

2x=140

x=140/2

x=70

Answer 2

Here, the formula to find x: a+b+c= 180
a=40
b= x
c= x
40+x+x=180
40+2x=180
2x=180-40
2x=140
x=140/2
x=70.

Check, a+b+c=180
40+70+70= 180.
