Answer:
x = 4
Explanation:
We require to find RT
Since ΔRST is right use the sine ratio to find RT
sin60° =
=

Multiply both sides by RT
RT × sin60° = 2
( divide both sides by sin60° )
RT =
= 4
-----------------------------------------------------------------------
Since ΔRTQ is right use the tangent ratio to find x
tan45° =
=

Multiply both sides by 4
4 × tan45° = x, hence
x = 4 × 1 = 4
That is x = 4
