Question

question number( iv )​

Answer 1

QUESTION:

5/sin x + 3/sin y -3cot y

ANSWER:

14

SOLUTION:

As, we know that

❭ sin=P/H

❭ cos=B/H

❭ tan=P/B

❭ cot=B/P

❭ sec=H/B

❭ cosec=H/P.

According to Question:

5/sin x + 3/sin y -3cot y

❭ 5/5/13+3/12/20-3×16/12

❭ 13+5-4

❭ 18-4

❭ 14

$\LARGE{ \underline{\underline{ \pink{ \bf{Required \: answer:}}}}}$

So, the answer will be 14.

Answer 2

QUESTION:

5/sin x + 3/sin y -3cot y

ANSWER: 14  

SOLUTION:

As, we know that

• ❭ sin=P/H
• ❭ cos=B/H
• ❭ tan=P/B
• ❭ cot=B/P
• ❭ sec=H/B
• ❭ cosec=H/P.  

$\LARGE{ \underline{\underline{ \pink{ \bf{according \: to \: question :}}}}}$

5/sin x + 3/sin y -3cot y

❭ 5/5/13+3/12/20-3×16/12

❭ 13+5-4

❭ 18-4

❭ 14  

$\LARGE{ \underline{\underline{ \pink{ \bf{Required \: answer:}}}}}$ 14

So, the answer will be 14.
