Correct Answer: 150°
Solution : Given, that $\triangle$ABC and $\triangle$DEF are congruent. AB = 6 = DE, BC = 8 = EF, and $\angle$B = 30° Since, $\triangle$ABC $\cong$ $\triangle$DEF ⇒ $\angle$A = $\angle$D By angle sum property in $\triangle$ABC, $\angle$A + $\angle$B + $\angle$C = 180° ⇒ $\angle$D + 30° + $\angle$C = 180° ⇒ $\angle$D + $\angle$C = 150° Hence, the correct answer is 150°.
