Triangle + triangle + square = 23

Triangle x square = 60

Triangle?

Square?

Square = 7.666

Triangle = 7.6666

Triangle x Square = ?

2 triangle+square=23

square=60/triangle

2 triangle+60/triangle=23

2 triangle^2+60=23 triangle

2 triangle^2-23 triangle+60=0

solving quadratic equation we get

triangle=15/2, 4

15/2 is not possible so triangle=4

square=15
