Well, darling, if you want to solve for "blank," you simply divide 90 by 120. So, 90 divided by 120 equals 0.75. There you have it, sweetie, the answer to your little math problem.
To find the increase from 55 to 90, you subtract 55 from 90. The calculation is 90 - 55 = 35. Therefore, 55 increased to 90 represents an increase of 35.
x2 - 2x + 55 = 90x2 - 2x - 35 = 0(x+5)(x-7) = 0x = -5, 7
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.
