How do you get rid of biting midges? To get rid of biting midges, don't water the plants in your house and garden too often. The soil needs to dry in between waterings, as the larvae of biting midges live in damp soil. Once the soil dries out completely, the larvae die.
On physical examination, check for the quadriceps angle, or Q-angle, which is the angle created between a line drawn from the center of the anterior superior iliac spine on the pelvis to the center of the patella and a second line from the center of the patella to the middle of the tibial tubercle.
Complementary angles mean that the two angles, when added together, equal 90Â°. Let's call the first angle x, and its second, complementary angle 2x. So, we have x + 2x = 90. Solving for x, we get x = 30. Since the first angle was called x, that means it's measurement is 30Â°. The second angle, 2x, is just twice the first angle, so its measurement is 60Â°.
