Point N is the Centroid of ∆WSC. If WN=30 and WC=60, Find TN, CA, and WA

• TN = 15, CA = 30, WA = 30
• TN = 60, CA = 30, WA = 30
• TN = 15, CA = 20, WA = 40
• TN = 60, CA = 20, WA = 40

Point N is the Centroid of ∆WSC. If TN=11, Find WN, and TW

• WN = 5.5 , TW = 16.5
• WN = 22 , TW = 33
• WN = 33 , TW = 44
• WN = 33 , TW = 22

The figure shows the drawing of a boat. Find the measure of angles 1, 2, and 3.
