What are the lengths of the missing sides of a 30-60-90 triangle if the longer leg of the triangle is 18 centimeter?
The longest side of the triangle will always be opposite the largest angle, which is 90° in this case. We can use the sine law to work out the other sides with that:
sin(90°) / 18 = sin(60°) / x = sin(30°) / y
1/18 = sin(60°) / x
x = 18 sin(60°)
x = 18√3 / 2
x = 9√3
1/18 = sin(30°) / y
y = 18 sin(30°)
y = 9
So the triangle has a sides of 9 and 9√3, with a hypotenuse of 18

What is the answer of the LCM 306090?
You cannot find the LCM of only one number, two or more are needed.
What is the LCM of 306090?
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
What is the least common multiple of 51015?
As presented in the question it looks like a single number 51015. The lowest common multiple of 51015 depends upon the other number(s) with which 51015 has common multiples, but it will always be one of the multiples of 51015, namely: 51015, 102030, 153045, 204060, 255075, 306090, ... However, I suspect that you wrote the question separating 5 10 and 15 by commas with no spaces following the commas (ie ``...multiple of 5,10,15'') - unfortunately due to limitations some punctuation (the comma being one of them) get stripped from questions. The lowest common multiple of 5, 10 and 15 is 30.
