The 15th parallel north is a circle of latitude that is 15 degrees north of the Earth's equatorial plane. It crosses the Saharan fringe (the Sahel) in Africa, three key peninsulars of Asia (between which parts of the Indian Ocean), the Pacific Ocean, an isthmus of Central America, the southern Caribbean and the Atlantic Ocean. In the Chadian-Libyan conflict of 1978 to 1987, its intra-Chad part came to be known as the "Red Line", separating opposing combatants, above all in Operation Manta. At this latitude the sun is visible for 13 hours, 1 minute during the summer solstice and 11 hours, 14 minutes during the winter solstice. (Wikipedia).

Learning to find the reference angle in the third quadrant

👉 Learn how to find the reference angle of a given angle. The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. To find the reference angle, we determine the quadrant on which the given angle lies and use the reference angle formula for the quadrant
