MathematicsTrigonometryGCSEAQA Created by: KittyLitterCreated on: 20-05-16 19:20 SOH Sin = Opposite ÷ Hypotenuse 1 of 9 CAH Cos = Adjacent ÷ Hypotenuse 2 of 9 TOA TOA = Opposite ÷ Adjacent 3 of 9 If the hypotenuse is 7, find the opposite, if the angle is 30˚ Sin(30) x 7 = 3.5 4 of 9 Find the opposite, if the adjacent is 4 and the angle is 50˚ Tan(50) x 4 = 4.77 (3.s.f) 5 of 9 If the angle is 25˚, and the adjacent is 5, what is the opposite? 5 ÷ Cos(25) = 5.52 (3 s.f.) 6 of 9 If the angle is 40˚ and the opposite is 6, what is the adjacent? 6 ÷ Tan(40) = 7.15 (3 s.f.) 7 of 9 If the adjacent is 5, and the hypotenuse is 7, what is the angle? Cos⁻¹ (5 ÷ 7) = 44.4˚ (1 d.p.) 8 of 9 If the hypotenuse is 8, and the opposite is 5, what is the angle? Sin⁻¹ (5 ÷ 8) = 38.7˚ (1d.p.) 9 of 9
