Answer:
i believe it is 98
Step-by-step explanation:
53+45=98
180-98=82
so angle FGH (the last angle of the triangle that has not been given a measurement) is 82° because angles in a triangle add up to 180°
180-82 =98
so x = 98 because angles on a straight line add up to 180
my explanation isn't very good sorry but I hope you understand x
