Question

What is the value of x?

Answer 1

x = 4

Explanation:

RST is a 30 60 90 right triangle

Ration of short leg : long leg : hypo. = a : a√3 : 2a

Given long leg = 2√3 so short leg = 2 and hypo = 2 * 2 = 4

RT = 4

Triangle RQT is a isosceles 45 45 90 right triangle

So RT = RQ = 4

Answer

x = 4
