Step-by-step explanation:
<u>Coterminal angles</u> have the same terminal sides in standard position.
a) To find an angle between and
, that is coterminal with
, we keep adding multiples of
until we get an angle within the specified range.
.
In some cases you would have to subtract in order to get the specified angle. That is when the angle given is positive.
b) This time we want to find an that coterminal with radians.
We keep subtracting multiples of until we get an angle measure within the specified range.
We have been given that Mark had $436.
Further, we are given that Chris has $86 lesser than what mark had.
Let us assume that Chris has $x. Therefore, we can set up an equation:
(Amount Chris had) + $86 = (Amount Mark had)
Upon subtracting 86 from both the sides, we get:
Therefore, the required expression that represent the amount of money that Chris had is .
