20 = 180 / 9
1620
20 goes into 180 nine times.
To find out how many times 19 goes into 180, you would perform long division. When you divide 180 by 19, you get 9 with a remainder of 9. This means that 19 goes into 180 nine times, with a remainder of 9.
9 x 20 = 180
The supplement of an angle x is equal to 180 - x. The measure of an angle that is nine times its supplement can be written as: x = 9(180 - x) You can then solve for the measure of the angle x: x = 1620 - 9x 10x = 1620 x = 162 Therefore, that angle which is nine times its supplement is itself 162 degrees.

9/20 = 81/180; 4/9 = 80/180...

Supplement of an angle measure x* be y*=(180-x*). Or x+y=180* for the problem x=9y => x+y = 9y+y=10y=180 => y=18* and x =172*
