a + 18 = 90 is a linear equation in one variable. Adding both sides by -18, we get a + 18 - 18 = 90 - 18 a = 90 - 18 = 72
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
90 + 90 + 60 = 240
54 + 560 + 90 = 704

Oh, dude, that's like basic math, right? So, if you're trying to figure out what number plus 90 equals 180, it's 90. Like, you just subtract 90 from 180 and you get 90. Easy peasy lemon squeezy.
90 minus 75 =15 therefore 15 + 75 = 90
54 + 560 + 90 = 704
To solve for tan x degree 90 you do a few things. First, if x equals 90, then this equals 1.5597 radian or 89.36 degrees. This is the easiest way to solve tan x degree 90.
The answer is .90. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
