The total number of miles Jeremy walked on a hike can be represented by using the formula. If and n represents the total number
of hours walked, what is the total distance Jeremy walked at the end of each of the first three hours? 2 miles, 5 miles, 8 miles
2 miles, 6 miles, 18 miles
2 miles, 3 miles, 4 miles
2 miles, 4 miles, 6 miles
We know that applying the law of cosines a² = b²+ c²<span> – 2*b*c*cos(A) </span> in this problem a=? b=20 c=9 A=90° so a² = b²+ c² – 2*b*c*cos(A) but cos (A)=0 a² = b²+ c²-----> 20²+9²----> a²=400+81----> a²=481-----> a=√481 a=21.93-----> a=22
