I already tried solving it by myself and I didn't get anything out of it lol
+128475 The unknown distance, D, at the top of the triangle on the right can be found as follows
D/ 14.4 = 14.4 /10.8 cross-multiply
10.8 * D = (14.4)^2
10.8 * D = 207.36 divide both sides by 10.8
D = 19.2
So....the total distance is 10.8 + 19.2 = 30 m
[ In a right triangle like this, the "14.8" is a geometric mean to the bases ]
