The boat had triangular sails.
The boat was small and had two triangular sails.
Tangent(theta) is sine over cosine, or y over x. x is 120. Theta is 32 and 37. y1 is height of cliff, and y2 is height of cliff plus flagpole.Tan(32) = y1 / 120, so y1 = 120 tan(32) = 75.Tan(37) = y2 / 120, so y2 = 120 tan(37) = 90.Height of flagpole is y2 - y1 = 90 - 75 = 15.All results rounded to nearest integer.
Not intentionally. They use a map book with notes of previous trips and water depth. The map book and notes are a pilot's prized possession and take years to fill out. Many of the pilots on the waterways can draw the whole river they operate with every turn and marker from memory. Its Skill and practice more than trig.
At the start his distance from the lighthouse is 100/tan(60) = 86.6 m. After 2 minutes his distance from the lighthouse is 100/tan(45) = 70.7 m. He travels 15.9 m in 2 minutes = 7.9 m per minute.
propeller
The oars or when a motor is used, the propellers on the shaft sticking in the water.

The boat goes back word because when you jump your tippy- toes are the only thing left on the boat, and then your feet push forward to do the rest, which makes the boat go backwards.
The most commen example given is stepping out of a row boat. You go forward, the boat goes backward.
because every action has an oppersite reactione.g.man pulls paddle backwardsoppersite reaction, man (in the boat) gets pushedforwards (with boat)
Its the forward part of the boat
When you row a boat on a pond, you are usually facing the back of the boat. Also, the oars are usually attached in the middle of the oar to the side of the boat. So if you pull the handle of the oar towards the front of the boat (towards you when rowing), the paddle of the oar is moving towards the back of the boat (the oar acts like a lever-arm). To move a boat forward, you actually have to move water backward! It's pushing water back that really moves the boat forward. So, when you pull the oar towards you, the paddle moves towards the back of the boat, and that pushes water towards the back of the boat, pushing the boat the opposite direction, which is forward! Just make sure to turn around once in a while because you're not looking where you are going!
Kayak has more in common with a racecar than with a boat when you look at how each word is spelled backwards. 'Kayak' and 'racecar' are both palindromes - they are spelled the same way forward and backward. The same cannot be said for the word 'boat'.
Example 1 A boat is stuck under a railway bridge. It cannot move forward or backward. The only way to remove the boat from under the bridge is to sink it. This can be done by drilling holes on the sides of the boat. When water enters the boat and occupies the air space, it become denser and sink.
In the realm of Hades, you jump down the chasm to the River Styx, where you meet the boatman, Charon. As you go down the river, there are usually 4 sets of the three perils : Rocks falling from the ceiling, Flaming Skulls, and River Monsters. To avoid the rocks, you can move forward or backward in the boat. To avoid the skull, you can jump or duck. To avoid the monster, you have to jump over it. The simplest way to get past them is to step forward or backward in the boat, and jump both the skulls and monsters. If you are knocked from the boat, you must start over.
The wind power pushes the boat with the different sails that can be changed by the direction of the wind and with the help of the rudder or even shifting body weight. Normally a zig zag route maneuvers helps in pushing the boat forward.
