Instructions: Find the measure of the indicated angle to the nearest degree. Please help?And now how to do it.

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.

Find the midpoint m of z1=(8+5i) and z2=(12+3i)
