7.5 x = 90x = (90 / 7.5) = 12
The value of x that solves the equation -243 = 90 - 9x is x = -12.
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
Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
90 x 10 = 900
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.
90 x 90 = 8,100
X + 35 = 90, therefore X = 90 - 35, so X = 55.
x equals -12 and y equals 1/4 of -12, so y = -3.
x would equal sqrt 90 or sqrt 9 x sqrt 10 = 3 root 10
3x-4x=12 that means -x equals 12 so x equals -12
