- 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.
Epoxy paint is suitable for fiberglass. There are many reasons that you may want to refinish a bathtub. Your tub may be old and worn, be an outdated color or no longer match your bathroom after renovating.
1 Reglazing or refinishing a bathtub is usually an option if the surrounding surfaces still look good, and the tub is still in relatively good condition. 2  Reglazing a bathtub is usually done in one day, typically in about 5-6 hours.3  If the process is done more quickly, it's more likely to fail and soon start to peel. Refinishing can be done with a brush and roller, but you'll get the best finish with a paint sprayer (about $100-$200 for a good basic model). 2  Some people are not happy with the long-term results of do-it-yourself bathtub refinishing.
