All
isosceles triangles are not similar. The pair of congruent angles
within one triangle is not necessarily congruent to the pair of
congruent angles within the other triangle.

Answer:

Step-by-step explanation:

» Collect second degree terms (x² coefficients) together and first degree terms (x coefficients) and constants

Answer:
100
Step-by-step explanation:
Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.
Since the sum of angles in a triangle is 180.
180-(25x2) will give you the last angle in one of the triangles.
The other angle is identical so the angle at the top of the other triangle will also be 130.
The sum of angles in a circle is 360.
Therefore, angle x = 360-(130x2)
X= 100
I did this last semester and I would remember it but unfortunately this was the only section I didn't study for the final bc we did one day on it. I'm sorry. Good luck.
