How to solve a 45 45 90 triangle trigonometry
WebTrigonometry (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 … WebTo solve, first multiply both sides by 20: 20 × 0.7071... = Opposite Finally: Opposite = 14.14m (to 2 decimals) When you gain more experience you can do it quickly like this: Example: How Tall is The Tree? Start with: sin (45°) = Opposite Hypotenuse We know: 0.7071... = Opposite 20 Swap sides: Opposite 20 = 0.7071...
