Question

Evaluate:cos 45°/sec 30°+cosec30°​

Answer 1

Look at the trigonometry table for special angles.

From here, substitute the values in:

$\frac{\sqrt{2} }{2} / \frac{2\sqrt{3} }{3}} + 2$

Simplify:

$\frac{3\sqrt{2} }{4\sqrt{3} } + 2$

Rationalize:

$\frac{\sqrt{6} }{4} +2$

And this is your answer.
