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°

The length of atrain car is 50.6 feet. This is 5.8 feet less than 6 times the width. What is the width?
hichkok12 [17]
∗ l = 50.6 ft
∗ w = ?

∗ The length is 50.6 feet. The question is saying that 50.6 is 5.8 feet less than 6 times the width.

∗ 6w - 5.8 = 50.6

∗ 6w = 56.4

∗ w = 9.4

Now lets check.

∗ If the length is 5.8 feet less than 6 times the width, and we found 9.4 as the answer, then;
6 times 9.4 - 5.8 should equal 50.6

∗ 6 • 9.4 - 5.8 = l

∗ 56.4 - 5.8 = l

∗ 50.6 = l


⋆The width is 9.4 feet⋆
