Answer:
D, 5/13
Step-by-step explanation:
The cosine of an angle is the adjacent side over the hypotenuse. In this case, that is 5/13. Hope this helps!

By definition we have that the volume is given by:
</span>

<span> Where,
w: with
l: length
h: height
Substituting values we have:
</span>

<span> Rewriting:
</span>

<span> We look for the roots of the polynomial:
</span>

<span> We discard the negative roots because we want to find dimensions.
Thus, the dimensions are:

Answer:
the dimensions in inches are:
w = 10.2 inches
l = 70.2 inches
h = 18.6 inches</span>
Answer:
Step-by-step explanation:
10). AD = BC [If ABCD is a parallelogram]
3x + 1 = 6x - 4
6x - 3x = 1 + 4
3x = 5
x = 
11). If ABCD is a parallelogram,
AB = CD
5x - 8 = 2x + 7
5x - 2x = 7 + 8
3x = 15
x = 5
12). If ABCD is a parallelogram,
AB = CD
AB║CD and BD is a transversal intersecting these parallel lines.
∠ABD ≅ ∠BDC [Alternate interior angles]
4x - 1 = x + 38
4x - x = 38 + 1
3x = 39
x = 13
So here's the rule from fractional exponents to radicals: ![x^{\frac{m}{n}}=\sqrt[n]{x^m}](https://tex.z-dn.net/?f=%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%5Em%7D%20)
<u>Looking at this rule, the denominator represents the root.</u>
Answer: 13/15
Step-by-step explanation:
1/5 + 2/3 = 13/15. Since 13/15 can’t be simplified, that’s your answer.
