Supplementary angle of 'x' is '180-x'

By the problem ,

x=4(180-x)+5

x=720-4x+5

5x=725

x=145

Therefore the angle is 145⁰.

∴the angle=4x+5.

they r supplements so:

x+(4x+5)=180

5x+5=180

5x=175.

∴x=35

its supplement is 145.

∴the measure of that angle = 145°.

hope it helps and pls mark this as best answer :)
