Question

find the value of X in the following figure
​

Answer 1

Answer:

1.value of x=180°-(40+40)=180-80=100°

4.value of x=60°

Answer 2

Step-by-step explanation:

1.

AB=AC (given)

angle ABC = angleACB(angles opposite to equal sides are also equal)

angleABC= 40°

angleABC+angle ACB+x= 180°(angle sum property)

40°+ 40° + x= 180°

x= 180° -80°

x= 100°

4.

x= 60°
