Answer:
x =4
Step-by-step explanation:
First we need to find the length of RT
Since the triangle on the left (RST) is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 60 = 2 sqrt(3) / RT
RT sin 60 = 2 sqrt(3)
RT = 2 sqrt(3) / sin 60
RT = 2 sqrt(3) / (sqrt(3)/2)
RT = 4
Now we can find x
Since the triangle on the right (QRT) is a right triangle, we can use trig functions
tan theta = opp /adj
tan 45 = x/ RT
tan 45 = x / 4
4 tan 45 = x
4 (1) = x
4 =x
