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

It is 90+90 = 180
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.
