Find the length of line segment x.
A)
4
B)
5
6
7

Answer:
x = 6
Step-by-step explanation:
4(x + 4) = 5(3 + 5) => Intersecting Secants Theorem
4(x + 4) = 5(8)
Open the bracket
4x + 16 = 40
Subtract 16 from each side
4x + 16 - 16 = 40 - 16
4x = 24
4x/4 = 24/4
x = 6
The length of the segment x is 6
The length of the segment x is calculated using the Intersecting Secants Theorem
This is represented as:
[tex]4(x + 4) = 5(3 + 5)[/tex]
Evaluate 3 + 5
[tex]4(x + 4) = 5(8)[/tex]
Open brackets
[tex]4x + 16 = 40[/tex]
Collect like terms
[tex]4x = 40 - 16[/tex]
Evaluate the like terms
[tex]4x = 24[/tex]
Divide both sides by 4
[tex]x = 6[/tex]
Hence, the length of the segment x is 6
