The answer is 7/40.
To solve, you have to find the LCM (least common denominator) for 5/8 and 4/5. 5/8= 25/40 and 4/5= 32/40. Subtract and you get 7/40. That is your answer.
Ben has mixed up the digit for millions and hundred thousands: he wrote 5
in the place for millions and 6 in the place for hundred thousands, but
it should be the other way. I think that he should exchange those two digits in the faulty report.
We know that
Two angles are said to be co-terminal <span>if they have the same initial side and </span>
<span>the same terminal side.
</span>
(52π/5)-----> 10.4π<span>
so
</span>(52π/5)-5*2π------> (2π/5)
the answer is
the positive angle less than one revolution around the unit circle that is co-terminal with angle of 52π/5 is 2π/5
2/3 c = d
multiply both sides by 3/2:-
c = (3/2) d
