Find x to the nearest tenth

Mathematics

<h3>Answer:  x = 14.3</h3>

=========================================================

Explanation:

We can find x using the law of sines, but first we need to find the missing angle. Let's call that y for now. The three angles of any triangle add to 180, so,

23+146+y = 180

169+y = 180

y = 180-169

y = 11

The missing interior angle is 11 degrees.

-----------

Now we can apply the law of sines.

sin(23)/x = sin(11)/7

7*sin(23) = x*sin(11)

x*sin(11) = 7*sin(23)

x = 7*sin(23)/sin(11)

x = 14.3343236728824

x = 14.3

Make sure your calculator is in degree mode.

Hello!

You have to find the area of the prism and the pyramid

rectangular prism is lwh

Put in the values you know

15 * 5 * 7 = 525

For a prism you use

\frac{lwh}{3}

Put in the values you know

\frac{15 * 5 *13 }{3}

Multiply

975/3

Divide

325

Add the values you know

325 + 525 = 850

The answer is D)850cm^{3}

Hope this helps!
