Answer:
value of x = 2.8
Step-by-step explanation:
By law of cosines,
![{a}^{2} = {b}^{2} + {c}^{2} - 2 \times b \times c \times cos(100) \\ {x}^{2} = {13}^{2} + {10}^{2} - (2 \times 13 \times 10 \times cos100) \\ = 169 + 100 - 260 \times 0.862 \\ = 269 - 260 \times 0.862 \\ = 7.758 \\x = \sqrt{7.758 } \\ = 2.785 \\ = approx \: 2.8](https://tex.z-dn.net/?f=%20%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%20%7Bb%7D%5E%7B2%7D%20%20%2B%20%20%7Bc%7D%5E%7B2%7D%20%20%20-%202%20%5Ctimes%20b%20%5Ctimes%20c%20%5Ctimes%20cos%28100%29%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20%7B13%7D%5E%7B2%7D%20%20%2B%20%20%7B10%7D%5E%7B2%7D%20%20-%20%282%20%5Ctimes%2013%20%5Ctimes%2010%20%5Ctimes%20cos100%29%20%5C%5C%20%20%3D%20169%20%2B%20100%20-%20260%20%5Ctimes%200.862%20%5C%5C%20%20%3D%20269%20-%20260%20%5Ctimes%200.862%20%5C%5C%20%20%3D%207.758%20%5C%5Cx%20%3D%20%20%5Csqrt%7B7.758%20%7D%20%20%5C%5C%20%20%3D%202.785%20%5C%5C%20%20%3D%20approx%20%5C%3A%202.8)
Answer:
<h2>The solution will be the shaded region for both.</h2>
Step-by-step explanation:
First we need to solve x + 3y = -18 and 5x + 2y = 14.
.
Putting the above value in the second equation, we get,
.
Hence, ![x = -18 - 3y = -18 -3\times\frac{104}{17} = -36.353](https://tex.z-dn.net/?f=x%20%3D%20-18%20-%203y%20%3D%20-18%20-3%5Ctimes%5Cfrac%7B104%7D%7B17%7D%20%3D%20-36.353)
