Answer: The required value of x is 98.
Step-by-step explanation: We are given to find the value of x from the given figure.
From the figure, we note that
the angles with measures 53° and 45° are remote interior angles of the triangle FGH and he angle with measure x° is the exterior angle.
We know that
the measure of an exterior angle of a triangle is equal to the sum of the measures of two remote interior angles.
Therefore, we get
Thus, the required value of x is 98.
