Question

What is the value of X? Enter your answer in the box.​

Answer 1

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
