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
so bac is 12+12√3=12(1+√3)ft
hence, the required result is
suppose we have two matrices a and b
we will assume the two matrices
we have to compute b-a which means subtracting corresponding elements of a from b.
