Answer:
Answers are below.
Step-by-step explanation:
Sin θ = Opposite / Hypotenuse
Cos θ = Adjacent / Hypotenuse
Tan θ = Opposite / Adjacent
1) sin (60) = 16/x
x = 16/(sin 60)
x ≈ 18.46
2) cos (45) = x/13
13 cos(45) = x
x ≈ 9.19
3) tan (53) = 10/x
x = 10/tan(53)
x ≈ 7.54
4) tan (21) = x/12
12 tan(21) = x
x ≈ 4.61
