Answer:
-3 < x ≤ 4
Step-by-step explanation:
x is between -3 and 4, but -3 is not included in the solution set:
Parallel
QR and ST both parallel to y axis.
hypotenuse=√(x²+(x√3)²)=√(x²+3x²)=√(4x²)=2x
sides are x,x√3,2x
smallest side=x
smallest angle=opposite smallest side
let smallest angle=α
cos α=(x√3)/2x=√3/2
