I love traveling with my family. Together we visited many different countries and cities. Last summer we were in America, we really liked it there. People there are very kind and friendly. <span>I love travel.</span>
Средняя линия треугольника делит стороны AB и CB на равные отрезки AM и MB, CN и NB соответственно. Следовательно, AB = AM + MB = √3 + √3 = 2√3, CB = CN + NB = 2√2.
По теореме Пифагора найдем сторону АС: AC² + CB² = AB²
AC² = (2√3)² - (2√2)² = 12 - 8 = 4
AC = 2
