The value of \cos 1200 ^ { \circ } + \tan 1485 ^ { \circ }​

Answers 1

Answer:

1/2

Step-by-step explanation:

= cos 1200° + tan 1485°

= cos [1080° + 120°] + tan [1440° + 45°]

= cos 120° + tan 45°

= cos (180° – 60°) + 1

= – cos 60° + 1

= [tex]\frac{-1}{2}+1[/tex]

=   [tex]\frac{1}{2}[/tex]   Ans/

Answer:

Haemocoel is the body cavity of arthropods and molluscs (e.g., cockroach and Pila), which is filled with blood. The haemocoel is an enlarged blastocoel, which greatly reduces the coelom (this is restricted to the cavities of the gonads and excretory organs). It acts as hydrostatic skeleton.

when metals react do they loose or gain electrons?

Answer:

gain electrons

Explanation:

thanks for asking questions

Answer:

In a reaction between metals and nonmetals, metals generally lose electrons to complete their octet and non-metals gain electrons to complete their octet. Metal atoms lose electrons from their outer shell when they form ions: the ions are positive, because they have more protons than electrons.
