can someone please help me with this retake question?? i don't know what i did wrong and i really need help

x = ___ units

Answer 1

x = 24

Step-by-step explanation:

First, find the length RT. Note that we can use the definition of sine 60:

sin 60° = (12√3)/RT

Solving for RT,

RT = (12√3)/sin60° , sin 60 = (√3)/2

= 24

Since ∆QRT is a 45°-90°-45° triangle, that means that

x = RT = 24
