Marcel (point J) lies in the grass and sees the top of the tent (point T) and, behind it, the top of the lighthouse (P). | TT '| = 1.2m, | PP '| = 36m, | JT '| = 5m. Marcel lies 15 meters away from the sea (M). Calculate the lighthouse distance from the sea - length of |P'M|.

Correct answer:

x1 =  135 m
x2 =  165 m

Step-by-step explanation:

5 / 1.2 = x1 / 36  x=36 1.25=150 m m=15 m  x1=xm=15015=135 m
x2=x+m=150+15=165 m
