SOLUTION: what is the exact value of (cos 45)(cos 30) + sin (45) + sin (30) ? I reduced it down to sqrt of 6 /4 + sqrt 6 / 4 is that right? and how would I write that, as a fin

Question 912090: what is the exact value of (cos 45)(cos 30) + sin (45) + sin (30) ?
I reduced it down to sqrt of 6 /4 + sqrt 6 / 4
is that right?
and how would I write that, as a final answer?
Someone please help

thanks!

Hi

θ	radians	sin θ	cos θ	tan θ

0°	0	0	1	0

30°	π/6	1/2	√3/2	√3/3

45°	π/4	√2/2	√2/2	1

60°	π/3	√3/2	1/2	√3

90°	π/2	1	0	─

(cos 45)(cos 30) + sin (45) + sin (30)

(√2/2)(√3/2) + √2/2 + 1/2

√6/4 + √2/2 + 1/2

(√6 + 2√2 + 2)/4
