Final answer:
The measurement of angle HIG in quadrilateral AGHI is 124 degrees.
Step-by-step explanation:
To find the measurement of angle HIG, we need to consider that the sum of the angles in a quadrilateral is always 360 degrees. We know that angle IHG is represented as 3x + 4, and angle IGH is represented as 2x - 24. Since segment HI is equal to segment GH, angle IHG and angle IGH are congruent. Therefore, we can set up the following equation:
(3x + 4) + (2x - 24) + (2x - 24) + (3x + 4) = 360
Simplifying the equation:
10x - 40 = 360
10x = 400
x = 40
Substituting x back into the expressions for angle IHG and angle IGH:
Angle IHG = 3x + 4 = 3(40) + 4 = 124 degrees
Angle IGH = 2x - 24 = 2(40) - 24 = 56 degrees
Since angle HIG is congruent to angle IHG and angle IGH, its measurement is also 124 degrees. Therefore, the correct answer is D) 40.
