Based on the figure, select all true equations. Angle A is 48 degrees
Angle C is 90 Degrees

A. Angle B is 42 degrees
B. Side a is the hypotenuse
C. sin A = a/c
D. tan B =b/a
E. cos B = a/c
F. This is not a right triangle, so right triangle trigonometry does not apply

E

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.
