Unknown Story

So, if its 5 o'clock and those camping lessons taught me anything... our angle of elevation with the sun is 65˚. And it being aligned with the top of the lighthouse means the angle of elevation to the top of the lighthouse is also 65˚
Frank and Linda keep walk around the lake and find this abandoned lighthouse, they want to know the height of it. If they stand 60 feet away, the sun perfectly aligns with the point of the roof. It is 3:00 o'clock.

Yeah, me too I thought it would be like 100 feet or so.
I thought it would be smaller than 128 feet!
Good point Linda!
Sure but if we jump to it we need to jump like 5 feet higher than the bottom of the rope, so we should calculate the length from our head to the rope four feet above the bottom, that way we dont fall off when we jump!
We should figure out the length from the edge of this to the rope and if its close enough we could jump to it.
Frank and Linda are returning to their campsite, instead of going through were they came from they decide to go through the other side and stumble upon a rope hanging above a river. They know that the distance from their eyes to the bottom of the rope is 4

I knew I couldn't jump more than 6 feet, darn it!!
