When told to find angles when equations are involving sin,cos or tan at a level a range will be provided. You have to find all the angles within the given range. Multiple angles will be found as there wil...

We know that 1m=1000mm

Therefore 1m^2= 1000^2 mm^2

Since 1/0.2=5 

1000^2 / 5= Answer

gradient is change in y over change in x.

if (x1,y1) and (x2,x1) are lines on a graph then the change in y is y2-y1 and change in x is x2-x1, and since they are both on the line y1=mx1+c and y2=mx2...
