Answer:

Let space straight T 1 space represent space tower space one space and space straight T 2 space represent space tower space two. Draw space CB space perpendicular space to space straight T 1. Angle space of space depression space is space 45 degree. So space using space alternate space angles space property space we space get angle straight C equals 45 degree  From space the space figure space we space can space see tan 45 degree equals straight x over 75 straight x equals 75 straight m  Height space of space straight T 1 space equals 75 plus 160 space equals 235 space straight m
