Because you must go all the way around the Earth in order to cross every possible
longitude, but you only need to go half-way around it ... pole to pole ... in order to
stand at every possible latitude.
And by the way . . . there are an infinite number of longitudes, that cover a range of
360 degrees, and an infinite number of latitudes, that cover a range of 180 degrees.
Because when you travel in longitude, you can go all the way around the Earth, 360 degrees, crossing new longitudes all the way . But when you travel in latitude, the farthest you can travel is from one pole to the other pole ... halfway around the Earth, 180 degrees. Once you reach the opposite pole, if you keep going farther, you're just crossing latitudes that you've already crossed once.
There are several ways to come at this answer, most of them way too technical and arcane to bother with. The easiest answer to state and understand may be simply the fact that each parallel of latitude goes all the way around the Earth, but each meridian of longitude only goes half-way around the Earth, so you need more of them to cover the whole Earth. Does that do anything for you ? And by the way . . . there are only 180 degrees of latitude.
Lines of longitude (meridians) run north/south and measure angular distance east and west of the prime meridian to a maximum of 180 degrees east or west. Lines of latitude (parallels) measure angular distance from the equator. The maximum is 90 degrees north or south of the equator.
The same as the total number of different lengths that can be measured on a3-foot ruler. If you name two longitudes, then no matter how close togetherthey are, I can always name another longitude that's in between yours. Sothere's no limit to the number of different longitudes that we can name.

There are 360 longitudes

360 - 179 = 181
Because there are 360 degrees in a circle. The world is assumed to be a globe that is formed from 360 degrees.

pick a number 181, 182, 183, etc to 359
A regular polygon will have 360 sides with exterior angles of 181 degrees.

It would depend on the specific map. On a globe, there are an unlimited number of specific latitudes between 0 and 90 degrees north (equator to North Pole) and 0 and 90 degrees south (equator to South Pole). Longitudes range from 0 to 180 east and 0 to 180 west from the Prime Meridian, with 180 east and 180 west being the same line (on which the International Date Line is based). The total circumference of the planet is 360 degrees, and it would appear as a circle viewed from above either of the poles. Each degree of longitude is about 111.32 kilometers wide at the equator. Degrees can be divided further into minutes and seconds, or to any accuracy of decimal degrees.
