Answer:
x = 36
Step-by-step explanation:
Tan (30) = opposite / adjacent
The opposite is known: it is 12 √3
Tan (30o) = 1 / √3
Tan(theta) = opposite/adjacent.
Opposite = 12
Adjacent = x
Cross multiply
1*x = 12*()^2
x = 12 * 3
x = 36
Using proportions, it is found that both spaces have the same brightness, as both have 3 candles per m².
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For Nayeli and Citlali, the rate of candles per m² is given by:
- N = 12/4 = 3 candles per m².
- C = 30/10 = 3 candles per m².
Hence both spaces have the same brightness, as both have 3 candles per m².

Is/of = %/100
Take what you know and plug into the proportion.
is/5 = 20/100
Cross multiply 5 and 20 and divide by 100
is = $1
20% of $5 = $1
