Value of X for point I is x = 0 ( we will use the similarity of triangles: since the point D is the line that is perpendicular to the y-axis and forms the right triangle with the line from the point E, which is perpendicular on the x-axis; those segments that also form a proportion of 3: 5 )After that we can find the length of the line:=√ ( 82 + 32) = √ 73 = 8.544 DI = ( 8.544 : 8 ) · 3 = 3.20775 n - the distance between the line from the point D and the point R:n2 = 3.207752 - 32 = 10.28966 - 9 = 1.28966 n = √ 1.28966 ≈ 1.15, and = 2 + 1.15 y = 3.15 Answer:)
