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>
Answer:
25
Step-by-step explanation:
20/4 = 5. 5 x 5 = 25
Answer:
30
Step-by-step explanation:
3000 = 100x
x = 30
Another way:
75/100 is in reality 3/4
and 3/4 of 40 = 30
40/4 = 10
10 * 3 = 30
