Princess' Scribepost for January 6, 2010
Question No. 4
4. Find the height of the pole where the guy wire is attached, to the nearest tenth of a metre. a² = c² - b² a² = 10² - 2² a² = (10x10) - (2x2) a² = 100 - 4 a² = 96 √a² = √96 a = 9.8
² - b²
It's 100 - 48 :)
ReplyDeleteuhm the answer is suppose to be 96 because 100-4= 64 ?
