anonymous · Answer

for part A simply show all the identigal angles are equal, i guess you can do that?

anonymous · Answer

Yeah, I got that. I'm stuck on part B

anonymous · Answer

for part B, the ratio of similar sides is 162/70, as given clearly,
so the distance between shoreline and the boat is 65* 162/70

If it makes it easier for you, see the opposite triangle as a reflection. Flip it around so it looks like this. Then see it again as a reflection.

This helps me when I solve equations. Arnab09 has done a really good job explaining so far.

If they both have 90 degree angles, and you know that when a line bisects the other line it forms 2 pairs of 2 equal angles, so once you get AA, you can say AAA.

But not necessarily SSS   (in this case for sure not so, )
