if you have the tools to measure the base as 3 feet across, and the angle of elevation as 65 degrees; .... why dont you just use the same measureing device to measure the height with?
OpenStudy (amistre64):
height to width is a tangent definition
OpenStudy (amistre64):
tan(a) = h/w
w tan(a) = h

thats the thing i dont no how to do that i done many this to try to get it but its never works
OpenStudy (amistre64):
whats the width?

idk it dont say
OpenStudy (anonymous):
on the width is 3 feet
OpenStudy (amistre64):
ok, lets use that
3 tan(a) = h
now whats the angle?

this is what is says....A refrigerator has a width of 3 feet. The angle of elevation from the bottom corner to the opposite corner is 65º. What is the height of the refrigerator
OpenStudy (amistre64):

i guess 65
OpenStudy (anonymous):
because it say corner
OpenStudy (amistre64):
good, then lets use that
3 tan(65) = h
and thats the exact height then
OpenStudy (anonymous):
it gives me 6.433
OpenStudy (amistre64):
yes

who lol thanks
OpenStudy (anonymous):
can u explan this..If the height of a refrigerator is 6 feet and the base is 3 feet, find the angle of elevation.
OpenStudy (amistre64):
it all rests on how we define the tan function in trig
OpenStudy (amistre64):
|dw:1336675137365:dw|
as such we can undo that with the arctan function
