Angle ABC and angle BD are complementary. The measure of angle ABC equals (3x + 4) degrees, and

the measure of angle CBD equals (5x +6). Find the measures of both angles.

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
