The fall of the Western Roman Empire typically. represents the beginning of the Middle Ages. Scholars divide the Middle Ages into. three eras: the Early Middle Ages (4 00â1000), the High Middle Ages (1 000â1300), and. the Late Middle Ages (1 300â1500).
For any triangle it is universal truth that addition of all three angles will be one eighty degree (1800). Mathematically, it can be expressed as: â p + â q + â r = 180Â°, If we are given two angles out of three then substituting these values, one angle can be calculated using above formula.
A 30-60-90 triangle has interior angles equal to 30, 60 and 90 degrees. This is always a right triangle with the 90-degree angle located opposite the longest side of the triangle and the 30 degree angle located opposite the smallest side. The sides of a 30-60-90 triangle are always in a 1:root 3:2 ratio with each other, where 2 represents the longest side of the triangle.
