Answer: 1) ASA
2) none
3) ASA
Step-by-step explanation:
In the first picture we have two angles and one included side of one triangle is congruent to corresponding two angles and one included side of another triangle, therefore by<em> ASA postulate of congruence</em> both triangles are congruent.
In the second picture , the two have two equal angles, the third angle of both triangles by using angle sum property =,
Now, two corresponding angles and one included side (10 units) of both triangles are congruent therefore by <em>ASA postulate of congruence </em>both triangles are congruent.
In the third picture, we have two triangle with one same vertex, then their vertical angles must be congruent.
Thus, in third picture, two angles and one included side of one triangle is congruent to corresponding two angles and one included side of another triangle, therefore by <em>ASA postulate of congruence </em>both triangles are congruent.

Answer:
x=4, y=4, λ=-16
Step-by-step explanation:
We have this 3x3 system of linear equations:
λ
λ
So, let's rewrite the system in its augmented matrix form
Let´s apply row reduction process to its associated augmented matrix:
Swap R1 and R3
R3-4R1
R3+R2
Now we have a simplified system:
x+y+0=0
0+4y+λ=0
0+0+2λ=-32
Solving for λ, x, and y
λ=-16
x=4
y=4
