Answer:
25% of 210:
73.5
-----------------
175% of 210:
83.33333333 ~~ (on and on forever)
Step-by-step explanation:
Slope of line l (m1)=5
Slope of line w(m2)=-1/5
Since,m1×m2=-1 , line 'l' and 'w' are perpendicular.
Since line 'k' doesn't intersect line 'l' ,they must be parallel b'coz they are in the same plane as well.
Here, 'l' is perpendicular to 'w' and parallel to 'k'....so w and k must be perpendicular to each other.
It can be proven:
Since l and k are parallel, their slopes are equal.
So, slope of k (m3)=5
Since m3×m2=-1 ,w and k are perpendicular.
Hence, angle between w and k is 90°

Answer:
Step-by-step explanation:
The given equation is of the form ...
ax² +bx +c = 0
where a=2, b=-1, c=-8.
The quadratic formula gives the solution to the above equation as ...
So, for your equation, the solution is ...
Comparing this to the form ...
we see ...
LCM always has to be bigger or the same than both numbers.
HCF always has to be smaller as a factor has to fit exactly in the original number.
So LCM will always be greater
