Answer:

False

Explanation:

The given equation is

$\cos(t)=(5)/(3)$

The range of values of the cosine function lies between
$-1\leq \cos(t) \leq 1$

But the given value is
(5)/(3)=1(2)/(3) . This does not belong to the given range.

Therefore there is no value of
so that
$\cos(t)=(5)/(3)$

holds.
