Question

sin 30 +cos 45 +tan 180​

Answer 1

Answer:

ans; $(\sqrt{2}+2)/2\sqrt{2\\}$

Step-by-step explanation:

sin30=1/2

cos45=1/$\sqrt{2}$

tan180=0

therefore

(1/2)+1/$\sqrt{2\\}$+0

$(\sqrt{2}+2)/2\sqrt{2\\}$

Answer 2

Step-by-step explanation:

• 30 is a standard angle, sin30 value is1/2
• tan18O= tan(90*2+0)

=tan0

=0
