Find an angle that is 9 times larger than adjacent to it.

Since two adjacent corners always form a flat angle, the sum of the adjacent angles is 180 °. Then, if we designate one of them for x, then the second, which we need to find, can be written as 9x. You can make an equation:

x + 9x = 180.

10x = 180.

x = 18 °.

Then the angle, which is 9 times greater than the angle x, will be:

18 * 9 = 162 °.
