Slope is given by the expression:

We can equal both slopes of mAC and mCE

Answer is B.
Answer:
⠀
Step-by-step explanation:
The triangle having two sides equal along with one different side is called an isosceles triangle.
⠀
- So, Let us assume the other sides (two equal sides) of the isosceles triangle as x. As the different side is already given in the question.
⠀
We know that,
- The sum of all angles of a triangle is 180°
⠀
So, According to the question :
⠀

⠀

⠀

⠀

⠀

⠀

⠀
Therefore,
- The measure of the two other angles of the isosceles triangle are 71° and 71°.
Answer: It is possible to draw different lines to approximate the same data. The line of best fit is only an estimate.
