find blip coordinates in circle radar

[XaskeL]

help me find blip coordinates on frames

ex, ey this blip position
142 distance from center in radar to the brink of radar
 

local camx,camy,_ = getElementPosition(camera)
		
local ex,ey = 1164.468, -948.094
local t = -math.deg(math.atan2(camx - ex, camy - ey)) 
local r = t < 0 and t + 360 or t

local movx = (math.sin(camrot-r) * 142)
local movy = (math.cos(camrot-r) * 142) 

dxDrawImage(centerx + movx - 12, centery + movy - 12, 24, 24, 'images/icons/4.png', 0, 0, 0, white, false)

Screen



I absolutely do not understand math, so I hope that someone will help.

I think you should take a look at these two:

I need to understand how to calculate the turn of the blip around the radar, as well as its position to the center of the radar
