(see diagram) the gradient of the line joining the origin to the point a is 1/2. the distance between a and the origin is sqrt 2205. what are the coordinates of a?

Let the coordinate of point A be (x,y) .

ANd the given slope is 1/2 .

That is

And the distance between O and A is sqrt 2205, that is

Substituting 2y for x, we will get

And we have

So the point is (42,21)

idk lol xd

step-by-step explanation:

ez do it yourself lazy

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
