Answer:

Option 4 is correct

x° + 126° = 180° and value of x is 54°

Step-by-step explanation:

Here, In a given Triangle two sides are equal i.e., Isosceles Triangle.

We know that, in a triangle the sum of all angles Is 180°.

If two sides are equal then also two angles are also equal of that sides.

Now,

63° + 63° + x° = 180°

x° + 126° = 180°

Now, To find the value of x

x° + 126° = 180°

x° = 180° - 126°

x = 54°

Thus, The value of x is 54°

FOR VERIFICATION ONLY:-

x° + 126° = 180°

54° + 126° = 180°

180° = 180°

Hence, L.H.S = R.H.S
