A car is driven eastward for a distance of 50 miles, then northward for 30 miles, and then in a direction 30 degrees east of north for 25 miles. Find the total displacement of the car from its starting point.(adsbygoogle = window.adsbygoogle || []).push({});

So I set up a vector diagram, starting at the origin. I did: 30^2 + 50^2 and took the square root of that to find the length of the first part. Then I added that to 25 and got 83.234, but the answer is 81.0. What am I doing wrong? Also how would you find the direction?

Thanks
