Since AB and BC are congruent, ABE is equivalent to CBE. ABE+CBE=ABC. So the answer would be 80 degrees.

Answer:

  (i) 55.59 km/h

  (ii) 3600 nautical miles ≈ 6670.8 km

  (iii) 30°N 29.3°E

Step-by-step explanation:

(i) The speed in km/h requires a units conversion.

  (30 kt/h)(1.853 km/kt) = 55.59 km/h

__

(ii) Here, we assume we're interested in the <em>distance traveled</em>. If the course is "due east", we presume that means it follows the 30° latitude line, so is not the shortest route between A and B. That is, the distance from A to B will be different from the distance traveled. (The shortest route from A to B is along a great circle.)

  distance = speed × time

  distance = (30 kt/h)(120 h) = 3600 nautical miles

  = (55.59 km/h)(120 h) = 6670.8 km

__

(iii) The radius of the 30° latitude line is ...

  (6370 km)(cos(30°)) = 3185√3 km ≈ 5516.58 km

The relationship between arc length (s) and central angle (α) is ...

  s = rα

So, the change in the vessel's longitude is ...

  α = (6670.8 km)/(5516.58 km) ≈ 1.20923 radians ≈ 69.28°

Then town B has longitude ...

  40°W -69.3° = -29.3°W = 29.3°E

The position of town B is about 30°N 29.3°E.

_____

<em>Additional comment</em>

The route supposedly taken by this sea vessel is from the middle of the North Atlantic to a town in northern Egypt, through the northern Sahara desert. The eastern end point is shown in the attachment.

Some spherical trigonometry is involved if you want to find the end point of the great-circle route of the same length.

Ben is 4 times as old as Ishaan. 6 years ago, Ben was 6 times as old as Ishaan
Svetlanka [38]

Answer:

The correct answer is - Ben is 8.

Since Ben is 4 times older than Ishaan, but also we know the fact that Ben is 6 years older than Ishaan, that leaves us with only one number as the possible solution, the number 8.

In order to get to the result we should find a number that multiplied by four and summed up with six, gives the same result.

4 x 2 = 8

2 + 6 = 8

Knowing now that the age of Ben is 8, we can also conclude that the number used for multiplying and summing, 2, is the number that represents the age of Ishaan.

Adam would use the following steps to round 11.3524 to the nearest tenth 11.3524-11.352-11.35-11.4 is adam's method a valid way
noname [10]

Answer:

Adam's way is correct

Step-by-step explanation:

11.3524 can easily be rounded to the nearest tenth because the number 4 cannot be rounded up. Any number below 4 cannot be rounded up and anything above five can be rounded up and that us why 5 rounded up transforms the 3 to a 4.

Hope this helped.
