How tall is the tree if a tree is supported by a cable 300 feet long. The cable runs from the top of the tree to the ground, where it forms a 45 degree angle?


Rate This Answer

Tree The sine of an angle theta in a right triangle (which is equivalent to the definition just given) is as the ratio of the lengths of the side of the triangle opposite the angle and the hypotenuse. So, sin(45)=height/300. From this you can conclude that the height is 212.13 ft. Keep doing the ChaCha!
