Answer:

Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that the quadratic formula is:

2. To solve the quadratic equation you must substitute the values. So, you have that:

Then you have:

3. Therefore, you obtain the following result:

To be congruent, the letters need to be in the same orientation.
Since YZ are the last two letters in XYZ, they would be congruent to the last two letters in LMN.
YZ is concruent to MN.
The tangent line is perpendicular to the radius, so will have slope
.. -1/2.5 = -0.4 . . . . . . corresponding to the 3rd selection
55 degrees
