Answer:
.................
Step-by-step explanation:
We can use the formula y2-y1/x2-x1 to find the slope.
1. 2-(-15)/12-5 gives us 17/7. The slope is 17/7.
2. -5-(-20)/6-(-18) gives us 15/24. We can simplify this to 5/8. The slope is 5/8.
3. -19-(-19)/-17-(-18) is 0/1. The slope is 0.
4. -17-3/-11-(-1) is -20/-10. The slope is 2.
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 = = 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
