No. Just because the angles are all less than 90 degrees, that doesn't tell us anything about the sides. The sides are all congruent ONLY if all 3 angles are 60 degrees each. If the angles all have different sizes, then so do the sides.

The equation of the linear regression is $\^ y = 3.58125\^x + 202.575$

<h3>Graphing tool</h3>

To determine the line of best fit, we make use of a graphing tool

See attachment for the graph of the line of best fit

<h3>The equation</h3>

From the graphing tool, we have the following calculation summary

Sum of X = 440
Sum of Y = 3601.5
Mean X = 44
Mean Y = 360.15
Sum of squares (SSX) = 1440
Sum of products (SP) = 5157

The regression Equation is then represented as:

$\^y = b\^x + a$

Where:

$b = \frac{SP}{SSX}$ and $a = \bar y - b \times \bar x$

$b = \frac{5157}{1440}$

$b = 3.58125$

Also, we have:

$a = \bar y - b \times \bar x$

$a= 360.15 - (3.58\times 44)$

$a = 202.575$

So, the linear regression equation is:

$\^ y = 3.58125\^x + 202.575$
