1.
For a vertical object of height
h
h
h
seen at angle of elevation
θ
\theta
θ
from horizontal distance
d
d
d
, which relation holds?
A
tan
θ
=
h
d
=
height
horizontal distance
\tan\theta = \frac{h}{d} = \frac{\text{height}}{\text{horizontal distance}}
tan
θ
=
d
h
=
horizontal distance
height
B
tan
θ
=
d
h
\tan\theta = \dfrac{d}{h}
tan
θ
=
h
d
C
sin
θ
=
h
d
\sin\theta = \dfrac{h}{d}
sin
θ
=
d
h
D
cos
θ
=
h
d
\cos\theta = \dfrac{h}{d}
cos
θ
=
d
h
