त्रिभुज ABC में, तीन कोण x, y और y + 10° हैं। साथ ही, 2x - 4y = 20° है।
प्रयुक्त संकल्पना:
एक त्रिभुज की सभी भुजाओं का योग 180° होता है
गणना:
x + y +y + 10° = 180°
⇒ x + 2y = 170° ...... (1)
पुनः, 2x - 4y = 20°......... (2)
1 और 2 से हमें प्राप्त होता है,
x = 340 + 20 /4
⇒ x = 90°
इसलिए यह एक समकोण त्रिभुज है।
∴ सही विकल्प 4 है
