Desde la parte superior de un faro de 70 m. de altura, el ángulo de depresión hasta un barco sobre le oceano es de 23°. ¿A qué distancia está el barco sobre la base del faro? Con ilustración

The distance between the lighthouse and the boat is: 164.91 meters

Step-by-step explanation:

Please look at the attached image to follow the triangular diagram generated with the info provided.

Notice that we can create a right angle triangle with the information presented in the problem. The height of the lighthouse (70 m) is the side opposite to a 23 degree angle. And what we need to find is the other side "D" perpendicular to the lighthouse, which stands for the horizontal distance between the lighthouse and the boat.

Since the sides involved are the opposite and the adjacent sides to the 23 degree angle, we use the tangent function to solve it:

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
