Answer:
AB ≈ 1095 yards
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AB² + BS² = AS²
AB² + 1300² = 1700²
AB² + 1690000 = 2890000 ( subtract 1690000 from both sides )
AB² = 1200000 ( take the square root of both sides )
AB = [tex]\sqrt{1200000}[/tex] ≈ 1095 yd ( to the nearest yard )
