Urgent! need someone to properly calculate for degrees because my calculator doesn't give right answer for some reason!

tan^-1 (2.3/1.4) = # degrees ( is not 1.02)

tan^-1 (17/39.8) = # degrees ( is not .40)

tan^-1 (4.3/15.1) = # degrees ( is not .27)

is this part of a question or something

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
