While facing north, Lisa and Aaron decide to hike to their campsite. Lisa plans to hike 5 miles due north to Lake Toftee before she goes to the campsite. Aaron plans to turn 38° east and hike 7.4 miles directly to the campsite. How far will Lisa have to hike from the lake to meet Aaron at the campsite?

Use law of cosines

a^2 + b^2 - 2ab cos (theta)     = c^2          c is the distance she will have to hike       a = 7.4 m  b = 5 m   theta =38 degrees
