(*base = b, h = height.) total height of tower = 10 +x Applying trigonometry in the triangle with angle 45, tan 45 = x/b (as both bases will be same) tan 45 = 1, 1 = x/b x = b (cross multiplication) now in the triangle with angle 60, tan 60 = total h/b (total h = x +10) root 3 = 10+x/b b(root3) = 10 + b b (root3 - 1) = 10 b = 10/root3 - 1 root 3 = 1.73 10/1.73-1 = b 10/0.73 = b b = 13.69 (approx) total h = x + 10 x = b total h = b+10 = 13.69 + 10 = 23.69
