Answer:
<u>The length of the longer segment of the 50 cm chord = 40</u>
Step-by-step explanation:
let the length of the longer segment of the 50 cm chord = x
so, the other segment = 50 - x
A chord of 50 cm bisects a chord of 40 cm
using the Intersecting Chords Theorem
so, x(50-x) = 20 * 20
50x - x² = 400
x² - 50x + 400 = 0
(x - 40)(x - 10) = 0
x = 40 or x = 10
<u>So, the the length of the longer segment of the 50 cm chord = 40</u>
6/10 is larger than 9/15's, good luck on your test!
30 miles is two-thirds of x (where x is the total distance)
<span>30 = (2/3)*x </span>
<span>30*3 = 2x
</span><span><span>90 = 2x
90/2 = x
45 = x
x = 45
The total length of his drive is 45 miles</span><span>
