Answer:

Step-by-step explanation:

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

= $\frac{11}{k}$

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

k = 2.947

k = 2.95 cm

b). cos(52°) = $\frac{16}{s}$

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

s = 25.988

s ≈ 25.99 cm

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

= $\frac{16.1}{q}$

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

q = 184.727

q ≈ 184.73 cm
