Answer:
289.877 ft
Step-by-step explanation:
You can draw the eagle and mouse by using a right triangle. You know that the height of the triangle will be 280 feet and the distance between eagle and mouse should be the hypotenuse. Since we know the angle and one side of the triangle, we can use trignometry (cosine(angle)=adjacent/hypotenuse). Plug in your values and solve for the hypotenuse.
Answer: There were 741 books in the library a year later.
Step-by-step explanation:
Given: Total books in library = 570
Number of books increased by 30%.
One year later, Number of books in the library = (Total books in library) + 30% x (Total books in library)
= 570 + (0.30) x (570)
= 570 (1+0.30)
= 570 (1.30)
= 741
Hence, there were 741 books in the library a year later.
