Question

What is the inequality of this question?​

Answer 1

Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own. But these things will change direction of the inequality: Multiplying or dividing both sides by a negative number. Swapping left and right hand sides.

Answer 2

The construction starts by extending the chosen side of the triangle in both directions. This is done because, this being an obtuse triangle, the altitude will be outside the triangle, where it intersects the extended side PQ. After that, we draw the perpendicular from the opposite vertex to the line
