Answer:
![5 \sqrt{2}](https://tex.z-dn.net/?f=5%20%5Csqrt%7B2%7D%20)
Step-by-step explanation:
![\sqrt{5} \times \sqrt{10} \\ = \sqrt{5} \times \sqrt[]{5} \times \sqrt{2} \\ = 5\sqrt{2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B5%7D%20%20%5Ctimes%20%20%5Csqrt%7B10%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B5%7D%20%20%5Ctimes%20%20%5Csqrt%5B%5D%7B5%7D%20%20%5Ctimes%20%20%5Csqrt%7B2%7D%20%20%5C%5C%20%20%20%3D%205%5Csqrt%7B2%7D%20)

Answer:
x =
and y = ![51.4^{o}](https://tex.z-dn.net/?f=51.4%5E%7Bo%7D)
Step-by-step explanation:
Known that he sum of angles on a straight line is
. From the diagram;
2y + x + y = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
x + 3y =
................ 1
Also,
2x + x + 2y = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
3x + 2y =
.............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y =
............. 4
7y = 360
y = ![\frac{360}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B360%7D%7B7%7D)
y = ![51.4^{o}](https://tex.z-dn.net/?f=51.4%5E%7Bo%7D)
substitute the value of y in equation 1,
x + 3y = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
x + 3(51.4) = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
x + 154.2 = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
x =
- 154.2
x = ![25.8^{o}](https://tex.z-dn.net/?f=25.8%5E%7Bo%7D)
Thus, x =
and y = ![51.4^{o}](https://tex.z-dn.net/?f=51.4%5E%7Bo%7D)
