From a height of 50 meters above sea level on a cliff, two ships are sighted due west. The angles
of depression are 61° and 28°. How far apart are the ships?

66.3 m

Step-by-step explanation:

Horizontal distance for the ship at angle 28= 50tan 28=94.03632327  m

Horizontal distance for the ship at angle of 61= 50tan 61=27.71545257  m

Distance apart=94.03632327 -27.71545257 =66.3208707  m

Therefore, the horizontal distance apart between the ships is approximately 66.3 m

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
