nope, no cosine
60/h=tanTheta
can i use cos(55degrees) = 60/h
which gives me 104.61.
Please check. Thanks!
60/h=tanTheta
The complementary angle to 35 degrees is 90 degrees minus 35 degrees, which is 55 degrees.
With that correction, the equation becomes:
cos(55 degrees) = Adjacent side / Hypotenuse
Here, the adjacent side is the height of the flagpole (opposite to the angle of 35 degrees), and the hypotenuse is the length of the shadow (60 feet).
Plugging in the values, the equation becomes:
cos(55 degrees) = height / 60
Now, to find the height, you can solve for it:
height = cos(55 degrees) * 60
height ≈ 44.21 feet
Therefore, the flagpole is approximately 44.21 feet tall.
