A photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the l

schepotkina [342]

The height of lighthouse is 52.2 yards

Solution:

Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41 degree

The diagram is attached below

Consider a right angled triangle ABC

AB is the height of the lighthouse

BC is the distance between the base of a lighthouse and Photographer

As per given, BC = 60 yards

Angle between the ground and the top of the lighthouse is 41 degree

Angle ACB = 41 degree

To find: height of lighthouse i.e AB = ?

We know that,

$tan(\angle ACB) = \frac{Perpendicular}{Base}$

Here Base is BC and perpendicular is AB

$\tan 41^{\circ}=\frac{A B}{B C}$

Substituting the values,

$\begin{aligned}&\tan 41^{\circ}=\frac{A B}{60}\\\\&0.8692=\frac{A B}{60}\\\\&A B=0.8692 \times 60=52.157 \approx 52.2\end{aligned}$

Thus the height of lighthouse is 52.2 yards

14)-30/-15=2

15)-20/5-5

=-4-5

=-9

16)90/-45=-2

17)-45/-15=2

18)-15 times 5/25

=-75/25

=-3

19)-15-(-45)/10

=-15+45/10

=30/10

20)5-5/-1

=0/-1

21)-(-15)/5

=15/5

22)-45-15/-15

=-60/15

=-4

23)-15+(-45)/-5

=-15-45/-5

=-60/-5

=12
