The total sound power, in decibels, from x objects each producing 50 decibels of sound power is given
by the function f(x) = 50 + 10 log x. Suppose each of
the x objects increases its sound power by 10
decibels, so that the new total sound power, in
decibels, is given by the function g(x) = f(x) + 10.

Given: hf || jk; hg ? jg prove: fhg ? kjg to prove that the triangles are congruent by asa, which statement and reason could be used as part of the proof? fgh ? kgj because vertical angles are congruent. jkg ? hfg because vertical angles are congruent. fhg ? jkg because right angles are congruent. hfg ? kjg because alternate interior angles are congruent.
