Triangle Sun Shade
right triangle trigonometry word problems..hardcore?
suppose you want the windows of your house built so that the eaves completely shade them from the sunlight in the summer and the sunlight completely fills the windows in the winter. The eaves have an overhang of 3 feet.
a. how far below the eaves should the top of a window be placed for the window to recieve full sunligh in mid winter, when the Sun’s noontime angle of elevation is 25 degrees?
bHow far below the eaves should the bottom of a window be placed for the window to recieve no sunlight in midsummer, when the Sun’s angle of elevation is 70 degrees?
c. How tall will the windows be if they meet both requirements?
i found it easiest to do this problem step by step, so that you get the other angles that you need as well as the sides.
Draw a vertical line to represent the side of the house, and at the top a horizontal line to represent the 3 foot overhang. There’s your right angle.
For part a draw the hypotenuse with an angle of 25. You have a right triangle, and the vertical side is 3tan25 = 1.4. The windows must be 1.4 feet below the eaves.
For part b your hypotenuse has an angle of 70 with the eaves, so the windows must be no more than 3tan70 feet below the eaves.
