the angles of pentagon are(3x+5)(x+16)'(2x+9)'(3x-8) and (4x-15) find the value of x? and hence find the measures of all the angles of pentagon?

The sum of all angles for a pentagon is 540°. Set the sum of your angles equal to 540 and solve for x. Then compute the individual angles using the different formulas, like x + 16.

13 x - 7 = 540
13 x = 547
It looks like x is not an integer.
