At a horizontal distance of 31 m from the bottom of a tree, the angle of elevation to the top of the tree is 22°. How tall is the tree?
Problem Because of prevailing winds, a tree grew so that it was leaning 4° from the vertical. At a point 35 meters from the tree, the angle of elevation to the top of the tree is 23' (see figure). Find the height h of the tree. 94° - 23° 35 m
the leaning tower of pisa is 55.9m tall and leans 5.5 deg from the vertical. if its shadow is 90.0m long, what is the distance from the top pf the tower to the edge of the shadow? assume that the ground is level.please help in details
Using a total station, a vertical angle of +5 28'12" was taken to a target set 1.700 m above benchmark A of elevation 175.926 m. The EDM slope distance to a reflector set over benchmark A was 443.355 m. From the same setup, a vertical angle of +11°42'12" was then taken to a target set 1.300 m over a point B at the top of the hill and an EDM slope distance of 341.682 m was taken to a reflector...

5. A uniform 8.0 m long ladder of mass 10.0 kg leans against a wall. The wall is smooth and the floor is rough. The coefficient of static friction between the ladder and the floor is 0.35 (i) Draw a sketch and free body diagram. (ii) Find the reaction force from the wall. (iii) Find the normal force at the ground. (iv) Find the minimum angle at which the ladder does not slip.
Aboud wants to calculate the height of a tree on the opposite bank of a river. to do this, he lays out a baseline 80 m long and measures the angles as shown below. The angle of elevation from A to the top of the tree is 28°. Calculate the height of the tree. 30° 85° 80 m А
