Question

Given STUV is a square, with SI = 2x + 13 and WU =
8.2 - 41, find x.
S
I
x=

Answer 1

x = 9

• all sides in a square is similar.

solve:

• 2(x) + 13 = 8(x) - 41

• 2(x) - 8(x) = -41 -13

• -6(x) = -54

• x = 9

Answer 2

Diagonals bisect eachother

$\\ \rm\Rrightarrow 2x+13=8x-41$

$\\ \rm\Rrightarrow 6x=54$

$\\ \rm\Rrightarrow x=54/6$

$\\ \rm\Rrightarrow x=9$
