2. Find the length (x) in the given figure. Solution: Using the theorems on tangent segments and secant segment. (OS)2 = RO * AO (OS)2 = (16+9) *9 (OS)2 = 25*9 (OS)2 = 225 (OS) = V225 (OS) = 15 o - 9 A 16 R 16 3. Find the length x in the figure. Solution: SI * HI = TI * FI 16* x = (10+ 8) *8 16x = 18*8 16x = 144 X = 144/16 x = 9 10

Answer:
T=x³+2x/x²−5x+9 h
Step-by-step explanation:
V=D/T
x²-5x+9 kph=x³+2x km/ T
T=x³+2x km÷(x²-5x+9 km/h)
=x³+2x/x²-5x+9 h (cancel the two kms)
=x³+2x/x²−5x+9 h
