Web2 days ago · Math Trigonometry Use the formula A = ½ ab sin C to find the area of the triangle with side a = 3.9, and angles B = 90º, C = 38°. Hint: Find b first. Hint: Find b … WebThe area A of a triangle with sides of length a, b, and c is given by the formula (5.2.5) A = s ( s − a) ( s − b) ( s − c) where s = 1 2 ( a + b + c). For example, suppose that the lengths of the three sides of a triangle are a = 3 f t, b = 5 f t, and c = 6 f t. Using Heron’s Formula (Equation 5.2.5 ), we get (5.2.6) s = 1 2 ( a + b + c)
