Answer:
Step-by-step explanation:
Jun Wei's monthly salary=1600 dollars=>annual salary= 1600*12=19200 dollars
Lixin's monthly salary = 6800 dollars=> annual salary= 6800*12 =81600 dollars
amt. donated by Jun= 1200 dollars
amt. donated by Lix = 4500 dollars
% donated by jun = (1200/19200)*100= 6.25% of his salary.
% donated by Lix = (4500/81600)*100= 5.5147% of his salary.
6.25%>5.5147%
Therefore, from the above, we can conclude that Jun Wei donated a higher percentage of his annual salary to the charity organisation.
Answer:
In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles. Wikipedia
