answer...

there are three types of triangle on the basis of sides.the triangle having all sides equal are called equilateral triangle and triangle having only two sides equal are called scalene triangle.Similarly, triangle having none sides equal are called isoseles triangle

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
