3/4√5-√3 + 2/4√5+√3 =b√3+a√5 find the value of b and a
Zielflug [23.3K]

Answer:

a = 5 / 4

b = 0

Step-by-step explanation:

3/4√5 - √3 + 2/4√5 + √3 = b√3 + a√5

3/4√5 + 2/4√5 + √3 - √3 = b√3 + a√5

5/4√5 + 0 = b√3 + a√5

0 + 5/4√5 = b√3 + a√5

b√3 = 0

b = 0 / √3

b = 0

a√5 = 5/4√5

a = 5/4√5 / √5

a = 5 / 4

Special segments in circles
pochemuha
If two chords intersect in a circle, then the products of the measures of the segments of the chords are equal.
I'm assuming that number up top is an 8. It's kind of blurry.

Since ten is a chord, and x is a segment of it, it can be expressed as x and 10 - x.
3(8) = x(10 - x)
24 = 10x -  x^{2}
x^{2}  - 10x + 24 = 0
(x - 6)(x - 4) = 0
x - 6 = 0     ....       x - 4 = 0
x = 6           ....       x = 4

4 or 6
