Figuring out lengths of triangle
Did you know?
WebEach triangle has a sum of 180°. Thus, the sum of the angles of any polygon is: S = ( n – 2) * 180. For example, the sum of all eight angles of an octagon is: S = (8 – 2) * 180 = 1080°. This formula works whether or not the polygon is regular and even works if the polygon is convex. The Red Cross symbol is a convex 12-gon. WebThis online calculator determines the lengths of triangle sides given one side and two angles using the law of sines. The law of sines, also known as the sine rule, states that the ratio of the length of a side of a triangle to the sine of the opposite angle is constant for all three sides and angles. The calculator takes as input the length of ...
WebExample. Find the size of angle a°. Step 1 The two sides we know are A djacent (6,750) and H ypotenuse (8,100). Step 2 SOH CAH TOA tells us we must use C osine. Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333. Step 4 Find the angle from your calculator using cos-1 of 0.8333: cos a° = 6,750/8,100 = 0.8333.
