Question

given l || m || n, find the value of x. (8x - 11)° (7x + 8)° answer attempt 1 out of 2 x =

Explanation:

Step1: Use property of parallel lines

Since \(l\parallel m\parallel n\), the corresponding - angles are equal. So, \(8x - 11=7x + 8\).

Step2: Solve the equation for \(x\)

Subtract \(7x\) from both sides of the equation \(8x - 11=7x + 8\). We get \(8x-7x-11=7x - 7x+8\), which simplifies to \(x-11 = 8\). Then add 11 to both sides: \(x=8 + 11\).

Answer:

\(x = 19\)
