Answer
(a) The temperature is $29^{\circ}C$
(b) The temperature is $302~K$
Work Step by Step
(a) We can convert the temperature to $^{\circ}C$:
$C = \frac{5}{9}(F-32)$
$C = \frac{5}{9}(84-32)$
$C = 29^{\circ}C$
The temperature is $29^{\circ}C$
(b) We can convert the temperature to kelvins:
$K = C+273$
$K = 29+273$
$K = 302~K$
The temperature is $302~K$.
