Answer:

98 degrees

Step-by-step explanation:

m<H = 45, m<F = 53

180 = 45 + 53 + (180-x)

82 = 180-x

x+82 = 180

x = 98

Answer:

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees. This means that

Angle F + angle G + angle H = 180

Therefore,

53 + 45 + angle G = 180

98 + angle G = 180

Subtracting 98 from the left hand side and the right hand side of the equation, it becomes

98 - 98 + angle G = 180 - 98

angle G = 82 degrees

The sum of angles on a straight line is 180 degrees. Therefore,

x + 82 = 180

Subtracting 82 from the left hand side and the right hand side of the equation, it becomes

x + 82 - 82 = 180 - 82

x = 98 degrees
