Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
त्रिकोण ABC मध्ये, AB = AC आणि ∠A = 70º.
वापरलेले सूत्र:
समद्विभुज त्रिकोणात, पायालगतचे कोन समान असतात.
त्रिकोणातील कोनांची बेरीज = 180º
गणना:
समजा ∠B = ∠C = x
∠A + ∠B + ∠C = 180º
⇒ 70º + x + x = 180º
⇒ 70º + 2x = 180º
⇒ 2x = 180º - 70º
⇒ 2x = 110º
⇒ x = 55º
∴ योग्य उत्तर पर्याय (4) आहे.
