In ∆ ABC, sides BC and BA are produced to D and E, respectively. If ∠ ACD = 120° and ∠ CAE = 130°, then what is the measure of ∠ ABC ?
- 65°
- 70°
- 75°
- 80°
∆ ABC में, भुजा BC और BA को क्रमशः D और E तक बढ़ाया गया है । यदि ∠ ACD = 120° और ∠ CAE = 130° है, तो ∠ ABC की माप क्या है ?
- 65°
- 70°
- 75°
- 80°
