Triangle Angle. Calculator Formula
WebI think there's only one answer that fits the question. You are right that arctan(7/-10) yields two answers in the range 0-360 degrees, but the vector u is in the second quadrant (u=-10i+7j), and so its angle cannot be 325 degrees, even though a vector with that angle has the same slope/tangent value. A vector with a direction of 325 degrees would be in the … WebOct 6, 2024 · Start by typing in a number, then click “Go to PVWatts results”. I entered “180” as my first azimuth angle. 5. Record the estimated system output. At an azimuth angle of 180° clockwise from true north, a solar power system at my location (with the default inputs) would generate an estimated 6,415 kWh per year. 6. christmas cards with santa and reindeer
