Challenge! Ready? Find the magnitude and direction of the vector. Round the length to the nearest tenth and the degree to the nearest unit. Diagram is not drawn to scale. http://assets.openstudy.com/updates/attachments/55b5b6b5e4b04559507b5a62-lollygirl217-1437972193870-as.jpg

    Hello again. Was this right? Find the magnitude and direction of the vector You could find the magnitude using pythagoras, or by using trig. The question asks for direction, which probably should be in the form NxxºE (North and so many degrees to the East). the magnitude is sin(A)= 6/M or M= 6/sin(A)= 6/sin(56.3)= 7.2 ft (If we use pythagoras: sqrt( 4^2 + 6^2) = sqrt(52)= 7.2 ft (Good!) answer: 7.2 ft in the direction N56.3ºE. They want the degree to the nearest unit, and the magnitude to the nearest tenth, so the real answer is 7.2 ft in the direction N56ºE.
