Is it possible for a quadrilateral to have ony 2 right angles if so

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.

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28
