WebbTrigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation … WebbSolution. 150° is located in the second quadrant. The angle it makes with the x -axis is 180° − 150° = 30°, so the reference angle is 30°.This tells us that 150° has the same sine and …
