Step-by-step explanation:
Is there a problem or something to show for it?
Theyre both divisible by 3
15n-18= 3(5n - 6)
Because 1/4 is a fractional number, it is also a ratio which means it is Rational. :)
Answer:
See below
Step-by-step explanation:
a = 15 sqrt 2 sin 45
= 15 sqrt 2 * sqrt( 2 ) /2 = 15 * 2 /2 = 15
sin 60 = a/c
sqrt(3)/2 = 15/c
c = 15 / ( sqrt(3)/2) = 30 / sqrt 3 = 30 sqrt 3 /3 = 10 sqrt 3
