Question

In the figure given below \(L_1 || L_2\) then x = __________.

• A. 30
• B. 45
• C. 60
• D. Cannot be determined

Answer 1

The Correct Option is B

Based on the information provided and the geometric relationships described:
1. Let angle \( \angle HBG = 2y \) and \( \angle BAF = 2y \) (corresponding angles are equal).
2. \( \angle FAC = y \) and \( \angle CAB = 180^\circ - 2y \) (sum of angles in a triangle).
3. \( \angle ABG = y \) and \( \angle ABC = 90^\circ - y \).
Given that \( \angle ACB \) (which is denoted as \( x \)) is not explicitly stated but inferred to be equal to \( \angle ABC \) due to geometric properties:
\( \angle ACB = \angle ABC = 90^\circ - y \).
Since \( 2x = 90^\circ \) (from the equation \( \angle ABC = 90^\circ - y \)), solving for \( x \):
\( 2x = 90^\circ \)
\( x = \frac{90^\circ}{2} \)
\( x = 45^\circ \)
Therefore, \( x = 45 \) degrees, which corresponds to answer option B 45.
