Which relationship is always correct for the angles p, q, and r of triangle abc? a triangle abc has angle abc labeled as q, angle bca labeled as r, and the exterior angle at a labeled as p. p + r = q p + q + r = 180 degrees p + q + r = 90 degrees q + r = p

The surface area of the triangular prism is .

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
