Correct Answer: 65° and 70°
Solution :
Given:
$\angle$ACD = 115°, $\angle$BAC = 45°
We know, $\angle$ABC + $\angle$CAB = $\angle$ACD
⇒ $\angle$ABC = 115° - 45°
$\therefore$ $\angle$ABC = 70°
$\angle$ACB + $\angle$BAC + $\angle$ABC = 180°
⇒ $\angle$ACB + 45° + 70° = 180°
$\therefore$ $\angle$ACB = 180° – 70° – 45° = 65°
Hence, the correct answer is '65° and 70°'.
