Answer:
<u><em>63 degrees</em></u>
Step-by-step explanation:
77 + 40 = 117
180 - 117 = 63
(All angles in a triangle add up to 180.)
Hope this helps!
Step 1:
<span>Calculate the effective thermal conductivity of the wall or ceiling:
</span>
K_eff = [ (13 ÷ 8)(0.12) + (16 - (13 ÷ 8)) × (0.04)] ÷ 16
K_eff =<span> [ 0.195 + 0.565] </span>÷<span> 16
</span>
K_eff = 0.76 ÷ 16
K_eff = 0.0475 W/ (m K)
Step 2:
Calculate <span>the interior ceiling area:
</span>Area of each of the interior side walls = <span>8.82 m x 8.64 m
= 76.2 m</span>²
Area of the interior ceiling = 8.64 m × <span>8.64 m
</span> = 74.6 m²
H = - k·A·(Δ - T) ÷ <span>(thickness)
</span>
H = - 0.0475 ÷ (379.45 × 20) ÷ 45/8
H = - ( - 0.95 × 379.45 ) ÷<span> 0.1429
</span>
H = <span>2.52 kW </span>
Answer:
Not, 1
Step-by-step explanation:
The complement of an event denoted as A', can be interpreted as not A. This means that elements not belonging to a A. In probabilistic term, if we have an event A, the complement is f A is the probability that event A does not occur.
The sum of an event A and its corresponding complement must equal to 1.
This is given by the complement rule ;
P(A) + P(A') = 1
Hence, P(A') = 1 - P(A)
