10 inches because there are 4 sides of a square so, if the perimeter is 40 inches, to figure out the side lengths you just have to divide the perimeter by 4
Answer:
13.5x - 5
Step-by-step explanation:
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°
