Question

For A I somehow got 41.05 but its 2.95cm can someone show me the working and what I did wrong?

Answer 1

Explanation:

a). tan(75°) =
`\frac{\text{Opposite side}}{\text{Adjacent side}}`

=
`(11)/(k)`

k =
`\frac{11}{\text{tan}(75)}`

k = 2.947

k = 2.95 cm

b). cos(52°) =
`(16)/(s)`

s =
`\frac{16}{\text{cos}(52)}`

s = 25.988

s ≈ 25.99 cm

c). sin(5°) =
`\frac{\text{Opposite side}}{\text{Hypotenuse}}`

=
`(16.1)/(q)`

q =
`\frac{16.1}{\text{sin}(5)}`

q = 184.727

q ≈ 184.73 cm
