Question

Cos 45 degree by sec 30 degree + cosec 30 degree

Answer 1

Answer:

0.6009361212

Step-by-step explanation:

cos45÷1÷cos30+1÷sin30

Answer 2

Answer:

2.8165

Step-by-step explanation:

value of Cos 45° is 1/√2

value of sec 30° is √3/

value of cosec 30° is 2

ACCORDING TO QUESTION

$cos \: 45 \: \div sec \: 30 + \cosec \: 30$

$\frac{ \frac{ \frac{1}{ \sqrt{2} } }{ \sqrt{3} } }{2} + 2 = \: \frac{2}{ \sqrt{6} } + 2$

by rationalization

$\frac{2}{ \sqrt{6} } + 2 \: = \: \frac{ \sqrt{6} }{3} \: + \: 2$

alternative form of

$\: \frac{ \sqrt{6} }{3} \: + \: 2$

is 2.8165
