Total area the square basic pyramid is
Where, a is side size of square and l is slant height.
Therefore area that square base pyramid is 144 square units.
In the diagram below, the edge of depression indigenous the optimal of the lighthouse come a speed boat is 27 degrees. The base of the lig
The angle of depression is constantly measured native the horizontal.
A triangle is created by the lighthouse, the ground and the boat. The edge of depression is no in the triangle, but it is same to the angle of key at the boat. (Alternate angle on parallel lines)
The edge at the height of the lighthouse, within the triangle is:
The street to the watercraft is the side opposite the edge of
while the height of the lighthouse is the adjacent side.

Tina is planning come fence in one area for she dog. She wants to produce a rectangle-shaped area the 1,600 square feet for she pet and ca
Using ideal formulas, the dimensions of a rectangle (length and width) can be provided to calculate the area of the rectangle and its perimeter. Utilizing the given information, those formulas provide two equations in the 2 unknowns of length and width. Using any of a variety of methods, the solution that satisfies both equations have the right to be found. That equipment will carry out numerical worths for the length and also width of the area for the dog.
A = 1600 = L·W
P = 160 = 2(L + W)
Solving the 2nd for L and also substituting right into the first, we get
L = 80 - W
1600 = (80 -W)·W
W² -80W +1600 = 0 . . . . . Subtract the right side, put in conventional form
(W -40)² = 0 . . . . . . . . . . . . Factor the equation
W = 40 . . . . . . . . . . . . . . . . This has actually one solution, that multiplicity 2
L = 80 - 40 = 40 . . . . . . . . Usage the previously emerged equation to uncover L
The dog pen will certainly be a 40-foot square.

The graph reflects another way to settle these equations. The equipment is the point(s) wherein the curves intersect. There is only one point: together = W = 40.
