PLEASE HELP A mouse is trapped in a maze. To find his way out, he walks 15 m, makes a 90° left turn, walks 8 m, makes another 90° left turn, and walks 10 m. What is the magnitude of the resultant vector?

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
