Answer:

hi

Step-by-step explanation:

Proportions are two fractions (or rational numbers) that are equal to each other.

Fractions are considered equal if both the numerator and denominator can be multiplied or divided by the same constant to get the other fraction.

BD and AC are chords that intersect at point Y.
Sindrei [870]

Answer:

4 units

Step-by-step explanation:

<u><em>The complete question is</em></u>

BD and AC are chords that intersect at point Y. A circle is shown. Chords B D and A C intersect at point Y. The length of B Y is 3, the length of Y D is 8, the length of A Y is x, and the length of Y C is 6. What is the length of line segment AY?

<u><em>The picture of the question in the attached figure</em></u>

we know that

The <u><em>Intersecting Chord Theorem</em></u> states that:  When two chords intersect each other inside a circle,the products of their segments are equal.

do

In this problem

(BY)(YD)=(AY)(YC)

substitute the given values

(3)(8)=(x)(6)

solve for x

24=6x\\x=24/6\\x=4\ units

therefore

The length of segment AY is 4 units

Plsssss help me with this angle circle problem what is x
kirza4 [7]

Answer:

x = 3

Step-by-step explanation:

Once again we want to use the relationship stated earlier

Where A * B = C * D

Once again imagine that the segments in the given problem have letters

A = x

B = 12

C = x + 1

D = 9

Now we create an equation using the relationship

12 * x = 9(x+1)

now we solve using basic algebra

step 1 distribute the 9 to the x and the 1

9 * x = 9x

9 * 1 = 9

now we have 12x = 9x + 9

step 2 subtract 9x from each side

12x - 9x = 3x

9x - 9x cancels out

now we have 3x = 9

step 3 divide each side by 3

3x/3=x

9/3=3

we're left with x = 3
