Answer:

11). x = 25.8°

12). x = 67.3°

Step-by-step explanation:

11). By using sine rule in the given triangle,

   cos(x) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

   cos(x) = \frac{27}{30}

   x = \text{cos}^{-1}(\frac{9}{10} )

   x = 25.84

   x ≈ 25.8°

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

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

    tan(x) = \frac{43}{18}

    x = \text{tan}^{-1}(\frac{43}{18} )

    x = 67.29°

    x ≈ 67.3°

WILL MARK BRAINLST 6 guys are watching sao but they only have 4 remotes and 6 tvs how much remotes will eatch guy get
IceJOKER [234]

Answer:

cant they just watch in pairs.

2 people on one tv

each pair would get one remote leaving one remote left over

if you divide the remotes umungst the 6 then they would only get a fraction of it. unless they buy 2 more remotes then I think that's the best solution
