Answer 1

Question-

Find the value of the following

1) 3 sin 17° sec 73°​

Answer-

3sin17 × sec73

sin17 =cos 90-17

= cos73

Then,

3cos73 × sec73

⇒ 3cos73 × 1

⇒ cos73

as, secO= 1

cos0 = 3*1

⇒ 3

Answer 2

Answer:

Step-by-step explanation:

3sin17sec73

sin17 =cos 90-17

= cos73

so,

3cos73sec73

3cos73*1

cos73

as, secO= 1

cosO

3*1
