A convex pentagon has interior angles with measures $x+1$, $2x$, $3x$, $4x$, and $5x-1$ degrees. What is the measure of the largest angle?

We have to make each convex sum final total equal to 540. So the answer is x = 0.26856 and $ = 36.08  in the equation through trial and error.  

Step-by-step explanation:

540/5 = 108 equal angles

call 179.4 largest = $5x-1$

if x= 35.88 then $ =0

if x = 560

then $ must equal 580-560=20

which is x 1.03.

Therfore $x +1s = 36.91

$2x$=73.9128

$3x$ =110.8692

$4x$ = 147.8256

$5x-1$ = 178.37

We change this to adding 1.03 to 179.4 = 180.4

then divide by 5 = 36.08

$x +1$ = 36.91 now 37.11

$2x$=73.9128 now 74.3248

$3x$ =110.8692 now 111.4872

$4x$ = 147.8256 now 148.6496

$5x-1$ = 178.37 now 180.4- 1.03 = 179.4

We add them together and find they add to 550.9716

We therefore can work out 550.9716 -540 degree = 10.9716

- and should have been 15 measures to begin with. To put right we can change 1.03 by subtraction to 1/15 of 10.9716 = 0.73144  1.03 - 0.73144 = 0.26856 therefore x = 0.26856 and $ = 36.08
