Prove that \( \triangle F G H \cong \triangle J K L \) are congruent. \( \begin{array}{l}F(4,6) G(5,7) H(7,4) \\ J(7,-4) K(2,-5) L(4,-2)\end{array} \)

2) If \( x-y=3, x+y=7 \), then \( x^{2}-y^{2}=\ldots \) \( (21,10,4,9) \)

Convert the angle to decimal degree form. Round your answer to three decimal praces \( \begin{array}{ll}\text { a) } 5^{\circ} 22^{\prime} 53^{\prime \prime} & \text { b) }-234^{\circ} 40^{\prime}\end{array} \)
