The true statement about the value of x is x > 43 . ( option C)
The exterior angle theorem states that the sum of interior angles is equal to the opposite exterior angle of the triangle.
If a and b are the two interior angles and x is the exterior then
c = a+ b
Therefore,
x = 41 + 43
x = 84
This means that out of all the statement in the option x is greater than 43 is the true statement ( x> 43) because 43 is not upto 84.
Other options are incorrect because they do not satisfy the value of x.
