Question

relating and calculating the measures of interior and exterior angles of a tr
what is the value of x?

Explanation:

Step1: Use the exterior - angle theorem

The exterior - angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non - adjacent interior angles.
In triangle \(FGH\), the exterior angle \(x^{\circ}\) is equal to the sum of the interior angles \(53^{\circ}\) and \(45^{\circ}\).
So, \(x = 53+45\)

Answer:

\(98\)
