90% of 55= 90% * 55= 0.9 * 55= 49.5
55% of 90= 55% * 90= 0.55 * 90= 49.5
The average of 55 and 90 is 72.5
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
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.
