For a right triangle with 60° angle, and hypotenuse h=10√3,
x=h*sin(60)=10√ 3 * √3/2 = 30/2=15
y=h*cos(60)=10√3 * (1/2) = 5√3
Meter is the best metric measurement.
3/4 x n=1......n equals 4/3.
In order for n to equal 1 you have to find a number that will make 3/4 a whole number after you multiply it. Usually in problems like these the answer is usually the fraction but flipped around. So 3/4 and 4/3....when you multiply the numerators you get 12 and when you multiply the denominator you get 12 so 12/12, which equals 1. hope that makes sense.
I wish I could help but I'm not good in math at all
The least common multiplier of 18 and 24 is 72. Because all of 18's multipliers do not match up with 24's multipliers until 72, it is the LCM
