Answer:
The angles do not have the same reference angle or the same sign.
Step-by-step explanation:
Given:
Statements related to the angle and the quadrant.
To Find:
Which statement gives best explanation
Solution:
Statements are follows:
1)The angles dont have same reference angle:
This statement is not totally true because some angles may have same reference angle . i.e depending upon the quadrant reference angle are founded .
2)Tangent is positive in second quadrant and negative in 4th quadrant:
Above half statement is false because tangent is positive in 3rd and 1st quadrant and negative in rest of quadrant.
3)Tangent is negative in 2nd quadrant and positive in 4th quadrant :
Similarly it is half negative as tangent is positive in 3 and 1 quadrant only.
4)The angles dont have same reference angle or the same sign.
This statement is true in terms of sign because reference angle will not have same sign .this gives best explanation.
Answer:
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
An ionic bond is held together by the electrostatic attraction between ions that are near one another. Electrostatic attraction is the attraction between atoms that have opposite charge and holds the atoms together in ionic bonds.
