Stvu is an isosceles trapezoid. if sv = 3x + 1 and tu = x + 21, find the value of x.

Definition of isos trapezoid=> A trapezoid with congruent legs.
Theorem=> Diagonals in a isosceles triangle are congreunt.
Answer=> SV is a diagonal and so is TU therefore they are equal.
Set aside=> 3x+1=x+21
Solve=> 2x=20
x=10

I’d say d hope it
