a norman window is a window with a semi-circle on top of regular rectangular window. (see the picture.) what should be the dimensions of the window to allow in as much light as possible, if there are only 12 ft of the frame material available?

the width of the window should be __ft, and the height of the window should be __ft.

The width of the window should be and the height of the window should be

Step-by-step explanation:

we know that

The circumference of a semicircle (window) is equal to

we have that

substitute and solve for r

so

the width of the window is equal to the diameter of the semicircle

so

The width of the window should be and the height of the window should be

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

$15 each
