It is that the angle has to be formed by two pairs of congruent/corresponding sides of the triangle
So it would equal to 8/10 and divide by 2 which you would get 4/5
Which equation is not equvilant It is c
First you would do $325.49 divided by 10 and you would get $32.55. so you would need $32.55 a week.
Area: If you multiply 2 1/3 by 5 2/5, you get an answer of about: 12.6, which means the area is about: 12.6in. squared.
Perimeter: If you add 2 1/3+ 2 1/3+ 5 2/5+ 5 2/5 you get an answer of about: 15.47. So, the perimeter is about 15.47in.
Note: If you aren't allowed to use a calculator on this test, you should probably multiply the numbers yourself so you get show the work and get the answer in a fraction, which is probably what they want. If you are allowed to use calculators, all the information you need is right here.
