Find x round to the nearest tenth

Mathematics

6 0

Answer:

83.0

Step-by-step explanation:

We have all three sides and the only thing we're missing is the X angle. And that's okay!

All you have to do is plug in the numbers into each variable. In this case if you are going to solve for X, you should use this equation.

$x^2=y^2+z^2-2yzcosX$

x = 17ft

y = 8ft

x = 16fi

Then you can algebraically solve for cosX, and then use the inverse of cosx to get the angle.

An amusement park has discovered that the brace that provides stability to the ferris

antiseptic1488 [7]

Answer:

Hence the correct answer is option (A) 4.708.

Step-by-step explanation:

Solution:-

Now, we need to find the angle of the sector by using sector formula,

$A = 28.25 ft^{2} \\r = 12ft.\\\\28.25 = \frac{\theta}{360^{o} } \times \pi \times 12^{2} \\\\\theta=\frac{28.25\times 360}{12 \times12 \times \pi} \\\\\theta =( \frac{70.625}{\\pi} )^{o}$

We now convert the angle to radian

$\theta = \frac{70.625}{\pi} \times \frac{\pi}{180}\\\\\theta = 0.39236 radian$

Now we calculate the length of arc by arc formula

$\theta=\frac{I}{12} \\\\0.39236 =\frac{I}{12}\\\\I = 4.708 feet.$

So, The length of steel that must be replaced is 4.708 ft.
