Find the value of x - this is circle segments.

Given:

Diagram of a circle and its two secant from an exterior point.

To find:

The value of x.

Solution:

We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.

Using the above property, we get

[tex](x+7)x=(2+2)2[/tex]

[tex]x^2+7x=(4)2[/tex]

[tex]x^2+7x=8[/tex]

[tex]x^2+7x-8=0[/tex]

Splitting the middle term, we get

[tex]x^2+8x-x-8=0[/tex]

[tex]x(x+8)-1(x+8)=0[/tex]

[tex](x+8)(x-1)=0[/tex]

Using zero product property, we get

[tex](x+8)=0[/tex] and [tex](x-1)=0[/tex]

[tex]x=-8[/tex] and [tex]x=1[/tex]

Side cannot be negative.

Therefore, the only possible value of x is 1.

2/6 - 7/20 as a proper fraction or mixed number

please help I will appreciate it
