Question

QRST is a rectangle If RT=4x-16 and SQ=x+5 find the value of x

Answer 1

x=7

Answer 2

if u draw the figure, RT and SQ turn out to be the diagonals of the rectangle
since diagonals of a rectangle are equal, so RT = SQ

==> 4x - 16 = x + 5
==> 4x - x = 5 + 16
==> x = 21/3 = 7

Answer 3

and this time, Harkirat is correct ^_^
