Atree standing vertically on level ground casts a 130 foot long shadow. the angle of elevation from the end of the shadow to the top of the tree is 21.8°. find the height of the tree to the nearest foot.

The height of the tree is 52 ft.

The height of the tree is calculated by the tangent law

tan21.8°=

tan21.8=h/130

h=52 ft

Therefore the height of the tree is 52 ft.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
