Answer 1

9). x = 36.9°

10). x = 18.3°

Explanation:

9). By applying tangent rule in the given triangle,

tan(x) =
`\frac{\text{Opposite side}}{\text{Adjacent side}}`

tan(x) =
`(9)/(12)`

x =
`\text{tan}^(-1)((3)/(4))`

x = 36.87°

x = 36.9°

10). By applying sine rule in the given triangle,

sin(x) =
`\frac{\text{Opposite side}}{\text{Hypotenuse}}`

sin(x) =
`(11)/(35)`

x =
`\text{sin}^(-1)((11)/(35))`

x = 18.32

x ≈ 18.3°
