Triangle ΔGHI with m∠G = 5°, m∠H = 75° and m∠I = 100°, is reflected across the y-axis to obtain ΔKLM. What is the measure, in degrees, of ∠L?

Answer:


\angle L = 100^(\circ)

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)
