HideShow resource information
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.)
