Any electrical engineers here?

I'm studying for the final classification of amateur radio licensing which is the Extra class and it's the hardest one. A lot of this test covers electrical engineering math and whatnot. Can someone tell me why reactance is measured with “j” as in -jX for capacitance and jX for inductance? Seems weird to have a variable as a final figure
