Someone answer this before the day ends please

M < 4 is the external angle of the triangle, and its adjacent interior angle, m < 2 is its supplement (the sum of their measures add up to 180°.

The Exterior Angle Theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles.

Remember that the two non-adjacent interior angles opposite the exterior angle are sometimes referred to as remote interior angles.

Therefore, the remote interior angles in this case are < 1 and < 3. Their sum is equal to m < 4.

Therefore, the correct answer is Option B) m < 1 + m < 3.
