In triangle ABC, AB=7 cm, BC=24 cm and AC=25 cm. Find the value of tan C + sin C + 2 cot A.
2.566
1.233
1.155
2.35
Answer: C
Since 7²+24²=25², angle B is 90°. Therefore, tan C=7/24, sin C=7/25 and cot A=7/24. The required value is 7/24+7/25+2(7/24)=1.155 approximately.
त्रिभुज ABC में AB=7 सेमी, BC=24 सेमी और AC=25 सेमी है। tan C + sin C + 2 cot A का मान ज्ञात कीजिए।

उत्तर: C
क्योंकि 7²+24²=25², इसलिए कोण B=90° है। tan C=7/24, sin C=7/25 और cot A=7/24। अतः आवश्यक मान 7/24+7/25+2(7/24)=लगभग 1.155 है।
