$\angle L = 100^{\circ}$

Step-by-step explanation:

Given

$\angle G = 5^{\circ}$

$\angle H = 75^{\circ}$

$\angle L = 100^{\circ}$

Required

Determine the measure of L after reflection across x-axis

When a shape is reflected across an axis, only the coordinates of the shapes is affected; the angles remain unaltered.

In other words, the measures of the angle will not change.

Hence:

$\angle L = 100^{\circ}$
