An aeroplane flies from point A (10 15’S, 370 E) to a point B directly North of A. the arc AB subtends an angle of 450 at the center of the earth. From B, aeroplanes flies due west two a point C on longitude 230 W.) (Take the value of π 22/ 7 as and radius of the earth as 6370km) (a) (i) Find the latitude of B (ii) Find the distance traveled by the aeroplane between B and C (b) The aeroplane left at 1.00 a. m local time. When the aeroplane was leaving B, hat was the local time at C?

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

113.42

i hope that is right.

step-by-step explanation:

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
