As we have discussed, a linear pair adds up to equal 180 degrees. If you know the measure of one of the two angles, then you can subtract that measure from 180 degrees to get the measure of the other angle. For example, in this picture, let's say that angle A measures 75 degrees.
Medicines for HIV and AIDS are sometimes called antiretroviral medicines. There are six different types of these medicines available to prescribe in the UK; they include: Nucleoside or nucleotide reverse transcriptase inhibitors - abacavir, didanosine, emtricitabine, lamivudine, stavudine and tenofovir.
