Answer:
Step-by-step explanation:
3). By sine rule,
sin(64°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(64°) = [tex]\frac{x}{15}[/tex]
x = 15[sin(64°)]
x = 13.48
4). By tangent rule,
tan(29°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{x}{35}[/tex]
x = 35[tan(29°)]
x = 19.4
5). By cosine rule,
cos(41°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{x}{22}[/tex]
x = 22[cos(41°)]
x = 16.60
