A compass is used to copy an angle.
The answer is C.
Answer:
Rehan;
76m
Step-by-step explanation:
Distance covered by running around square park :
Perimeter of square = 4s ; s = side length of square
Perimeter = 4 * 42m = 168 m
Total distance covered = 168m * 3 = 504m
Distance covered by running around rectangular park :
Perimeter of rectangle = 2(l + w) ;
Perimeter = 2(40 + 18) = 2(58) = 116 m
Total distance covered = 116m * 5= 580m
580m - 504m = 76m
Rehan covered more distance
25% decrease because if you multiply 20x.25 you get 5 and you minus the 5 from 20 books and you get 15 books
It not a right angle or an obtuse angle, so it has to be a acute angle, so angle x would be 50 or 55 degrees.
right angle:90 degrees.
obtuse angle: greater than 90 less than 180.
acute angle: less than 90 degrees.
3/10 * 9/9 = 27/90
5/9 * 10/10 = 50/90
77/90 which is about 3/4 mile!
