alleryThe height of a pole that casts a shadow equal to its own length is found at the time when the sun is at
A30 degrees
B75 degrees
C60 degrees
D45 degrees
Answer & Solution
Correct answer: D. 45 degrees
1. Pole height = shadow length means tan(theta) = 1.
2. arctan(1) = 45 degrees.
3. Hence the sun is at 45 degrees.
