Question

parallel lines e and f are cut by transversal b. what is the value of x? 1 5 25 37 (2x + 10)° (3x - 15)°

Explanation:

Step1: Use the property of alternate interior angles

Since parallel lines \(e\) and \(f\) are cut by transversal \(b\), the alternate interior angles are equal. So, \(2x + 10=3x - 15\).

Step2: Solve the equation for \(x\)

Subtract \(2x\) from both sides: \(2x+10 - 2x=3x - 15-2x\), which simplifies to \(10=x - 15\).
Then add \(15\) to both sides: \(10 + 15=x-15 + 15\), so \(x = 25\).

Answer:

\(25\) (the third option)
