Answer:

GH = 6 units

Step-by-step explanation:

Calculate GC using Pythagoras' identity in right triangle GCE

GC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )

GC = $\sqrt{225}$ = 15

GH + HC = GC ← HC is the radius of the circle and HC = 9, thus

GH + 9 = 15 ( subtract 9 from both sides )

GH = 6

Step-by-step explanation:

Step 1: Define

Point (6, 8)

Point (5, 5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [SF]: $\displaystyle m=\frac{5-8}{5-6}$
[Fraction] Subtract: $\displaystyle m=\frac{-3}{-1}$
[Fraction] Divide: $\displaystyle m=3$
