In an equilateral triangle, all three angles are equal and each measures \( 60^\circ \). Since one of the angles in \( \triangle ABC \) is given as \( (5x - 5)^\circ \), we can set up the equation: \[ 5x - 5 = 60 \] Solving for \( x \): \[ 5x = 60 + 5 \] \[ 5x = 65 \] \[ x = \frac{65}{5} = 13 \] So, the correct value for \( x \) is \( 13 \).
