30.5
10 to the 2nd power is 100
3050/100 = 30.5
First you need to find the common denominator. both 6 and 7 go in to 42 evenly
multiply 5/6 by 7 to get 35/42
multiply 2/7 by 6 to get 12/42
subtract 12 from 35 to get 23
23/42
B. As all the sides are different lengths and angle f is bigger than 90 so it is obtuse
Hope this helps
