The length of a in the triangle to the nearest tenth is 8.1 units.
<h3>How to find side of a triangle?</h3>
The side a of the triangle can be found using cosine formula.
Therefore,
a²= b² + c² - 2bc cos A
a² = 10² + 12² - 2 × 10 × 12 cos 42°
a² = 100 + 144 - 240cos 42
a² = 244 - 178.354758115
a = √65.6453
a = 8.10217871933
a = 8.1

Based on the function shown on the graph, the statement that is true is: <em>D. The candle started at 9 mm and shrinks 5 mm every 4 minutes</em>.
<h3>What is a Function?</h3>
A function is a relationship between input and output values.
On a graph, the average rate of change represents the unit rate, while the point where the line intercepts the y-axis is the initial value or starting value.
Therefore:
The starting value = 9 mm (the candle length when it started burning).
In conclusion, based on the function shown on the graph, the statement that is true is: <em>D. The candle started at 9 mm and shrinks 5 mm every 4 minutes</em>.
