Find the value(s) of the variable(s). Write your answer(s) in simplest radical form.

Step-by-step explanation:

12). By applying Pythagoras theorem in the given right triangle,

      Hypotenuse² = (Leg 1)² + (Leg 2)²

      x² = 7² + 7²

      x² = 2(7)²

      x =

      x =

13). By sine rule,

      sin(60)° =

      y =

      y = 18

      By cosine rule,

      cos(60)° =

      x =

      x =

14). By applying Pythagoras theorem in the given right triangle,

      12² = x² + x²

      144 = 2x²

      72 = x²

      x = √72

      x = 6√2
