To express the value of the arc secant of the square root of 2 you must first express its cross multiplication process that having variable x as its total then you will came up with sec(x) =sqrt(2) then remember that sec() is equals to 1/cos(x), then its is 1/cos(x) = sqrt(2) then use the special triangle principles withe side length of 1,1 and sqrt(2) and the value of that is pi/4 so x= pi/4 then arcsec(sqrt(2)) = pi/4.

S is in between T and U. ST = x + 4 and SU = 2x. TU = 16. Find the value of x.

You know the total length ST and SU, so to find x you would write an equation. This would be: x+4+2x=16 Combine like terms: 3x+4=16 Subtract four from both sides: 3x=12 Divide both sides by three: x=4
