O = opposite‚ A = adjacent and H = hypotenuse. sin θ = 1. The angle of elevation of the top of a tree from a point on the ground 10m from the base of the tree is 28◦ . What is the height of the tree? Solution We need to find the height of tree which is opposite an angle of 28◦ .Thus O tan θ = A O = A tan θ height of tree = 10 × tan 28◦ =⇒ height of tree = 5.3m 1d.p. 2. Using a surveying instrument 1.6m high‚ the angle of elevation of the top of a tower is measured to be 55◦ from a point

This spherical shape of blood in flight is important for the calculation of the angle of impact (incidence) of blood spatter when it hits a surface. That angle will be used to determine the point from which the blood originated which is called the Point of Origin or more appropriately the Area of Origin. A single spatter of blood is not enough to determine the Area of Origin at a crime scene. The determination of the angles of impact and placement of the Area of Origin should be based on the consideration

describing how the three quadrilaterals have the same and different characteristics. In a rhombus‚ opposite sides congruent‚ opposite angles congruent‚ consecutive angles supplementary and the diagonals bisect each other. In a rectangle‚ all angles are congruent and the diagonals are congruent. In a square‚ all angles are right angles the sum of the interior angles of a square will always be 360 degrees. A square is a rectangle‚ while a rectangle is not a square. A square is under the category of
