What is a supplementary angle example? Supplementary angles are those angles that measure up to 180 degrees. For example, angle 130° and angle 50° are supplementary because on adding 130° and 50° we get 180°. Similarly, complementary angles add up to 90 degrees. The two supplementary angles, if joined together, form a straight line and […]

What happens to the mass if you double the volume? If a mass and volume is doubled, what happens to the density? It will stay the same because the 2 and 2 would cancel out and we’d get the same density as the orignal value. Density is given as mass/volume -(1). IN your question the […]
