Answer:
Step-by-step explanation:
sin 45 = x/12
x = 12 sin 45
x = 6√(2)
answer is D
Answer:
135
Step-by-step explanation:
The given expression is
![\frac{2 {x}^{2} }{x} +x(100 - 15x)](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20%7Bx%7D%5E%7B2%7D%20%7D%7Bx%7D%20%2Bx%28100%20-%2015x%29)
From the question, x=5
So,by substitution,we obtain
![=\frac{2({5}^{2})}{5} +5(100 - 15(5))](https://tex.z-dn.net/?f=%20%3D%5Cfrac%7B2%28%7B5%7D%5E%7B2%7D%29%7D%7B5%7D%20%2B5%28100%20-%2015%285%29%29)
![=\frac{2(25)}{5} +5(100 - 75))](https://tex.z-dn.net/?f=%20%20%3D%5Cfrac%7B2%2825%29%7D%7B5%7D%20%2B5%28100%20-%2075%29%29)
![=2(5)+5(25)](https://tex.z-dn.net/?f=%20%20%3D2%285%29%2B5%2825%29)
![= 10+125](https://tex.z-dn.net/?f=%20%3D%2010%2B125)
![= 135](https://tex.z-dn.net/?f=%20%3D%20135)
Hence the answer is 135
Hi Vance :)
a=leg unknow
b=leg
c=hypotenuse
a²+b²=c²
a²=c²-b²
a²=145² - 144²
a²=21,025 - 20,736
a²=289
a=√289
a=17
unknow leg = 17 units
