10 x 10 = 100 80 x 80 =6400 6400-100= 6300 so that would have to be 3150ft.
im sorry but i know x=6 if that helps
So 4.5 is equal to 4 and 1/2
u can convert that to 9/2
then to get the reciprocal you flip the denominator and numerator
this gives u 2/9
Step-by-step explanation:
5(tanx)^2 -2 +tanx=0
let tanx=y
5y^2 + y-2=0
y=0.5403 or y= -0.7403
tanx=0.5403
x=arctan(0.5403)
x=28.38°
or
tanx=-0.7403
x=arctan(-0.7403)
x=143.49°
8/3
divide both sides by 3 and you get x=8/3
