Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. 65°F because we assume that at this temperature we do not need cooling or heating.
In our case the daily mean temperature is 83°F and X is the number of cooling-degree days.
X=83-65
X=18

[Note that you don't have to evaluate k to solve the problem]

$x = \frac{kuv}{(u+v)}$

That means that

$x \frac{(u+v)}{(uv)} = k, a \: constant$

So, you want $x$ such that

$x \frac{(3+3)}{(3 \times 3)} = 3 \frac{(3+1)}{(3 \times 1)}$

$x=6$

Answer:

5. 540°

Step-by-step explanation:

m<a + m<c = 180°

m<h + m<f = 180°

m<k + m<m = 180°

Then m<a + m<c + m<h + m<f + m<k + m<m = 180° x 3 = 540°
