bam bam and pebbles escape from the playpen they start crawling away, making an angle of 55 degree with each other .if bam bam crawls at ar ate of 60cm a min and pebbles crawls at 85 how far apart
Use the law of cosines. After 1 minute, the distance d will be
d^2 = 60^2 + 85^2 - 2*60*85 cos55°
Find that d, then just multiply by the number of minutes they crawled.
