Final answer:
The measure of angle ZF in triangle FGH is approximately 8.1 degrees.
Step-by-step explanation:
To find the measure of angle ZF in triangle FGH, we can use the trigonometric relationship between the sides of a right triangle. Since angle H is 90 degrees, triangle FGH is a right triangle. We can use the tangent function to find the measure of angle ZF:
tan(ZF) = HF / FG
tan(ZF) = 1.4 / 9.9
ZF = arctan(1.4 / 9.9)
ZF ≈ 8.1 degrees
