Hello!
∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:
∠E + 119 = 180
Now subtract 119 from both sides of the equation:
∠E = 61
We have now proven that ∠E is equal to 61 degrees.
I hope this helps!

Answer:
3x^2-1
Step-by-step explanation:
A. Prove that QR ≅ QR by reflexive property
Nikki is going to use <em>SSS Property</em>, which is Side, Side, Side. This means that, given two pairs of sides are congruent, you will have to find out the last side, which is the same side. This means that it is congruent with itself (since both triangles share the same side), and uses the reflexive property.
hope this helps
