6. Given:
`θ = 30°`
`a = 4 cm`
Find: ` sin θ, cos θ, tan θ ,b and c`
6. Given:
θ = 30°
a = 4 cm
Find: sin θ, cos θ, tan θ ,b and c  User Calculator
`sin30° = 0.5`
`cos30° = 0.866`
`tan30° = 0.577`
`b = 6.932 cm`
`c = 8 cm`
`sin30° = 0.5`
`cos30° = 0.866`
`tan30° = 0.577`
`tan30° = a/b` where `a = 4 cm`
`b = a/(tan30°) = (4 cm)/0.577 = 6.932 cm`
`sin30° = a/c ` where `a = 4 cm`
`c = a/(sin30°) = (4 cm)/0.5 = 8 cm`
