Answer:
3√2
Explanation:
Find the diagram attached
Sine the base of the triangle are divided equally the opposite angle to the sides will be 45 degrees
Considering one of the right angles triangle;
Hypotenuse = x
Opposite = 3
Angle theta = 45 degrees
According to SOH CAH TOA
sin theta = opp/hyp
sin 45 = 3/x
x = 3/sin45
x = 3/(1/√2)
x = 3 * √2
x = 3√2
Hence the value of x is 3√2
