A ship is sailing due north. At a certain point, the bearing of a lighthouse 3.83.8 km away is N38.138.1degrees°E. Later on, the captain notices that the bearing of the lighthouse has become Upper S 33.3 degrees E. S33.3°E. How far did the ship travel between the two observations of the lighthouse?

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
