- the measure of angle 3 is 115 degrees because angles 1 and 3 are a pair of vertical angles. - angles 1 and 2 are a linear pair, so their sum is 180 degrees; therefore, the measure of angle 2 is 180 - 115 = 65 degrees.

We have a 5000 gal fiberglass pool with heater, that slowly develops stains (brown or tan) on walls, pH 7.4, TA 120. These stains can easily be removed by a stain remover (concentrated ascorbic acid), together with a metal treatment. After treatment, pump is run for 12 hours then filter is backwashed and new DE added.
