Answer with explanation:
For, a Matrix A , having eigenvector 'v' has eigenvalue =2
The order of matrix is not given.
It has one eigenvalue it means it is of order , 1×1.
→A=[a]
Determinant [a-k I]=0, where k is eigenvalue of the given matrix.
It is given that,
k=2
For, k=2, the matrix [a-2 I] will become singular,that is
→ Determinant |a-2 I|=0
→I=[1]
→a=2
Let , v be the corresponding eigenvector of the given eigenvalue.
→[a-I] v=0
→[2-1] v=[0]
→[v]=[0]
→v=0
Now, corresponding eigenvector(v), when eigenvalue is 2 =0
We have to find solution of the system
→Ax=v
→[2] x=0
→[2 x] =[0]
→x=0, is one solution of the system.
Factor both numbers down, take all the prime numbers from the factorized 21 and 12 and multiply them
2*2 x 3 x 7

Answer:
<h2>Complementary angles.</h2>
Step-by-step explanation:
The graph is attached.
Notice that 
, 
and 
, by given.
, by sum of angles.
, by supplementary angles definition.
Which means,
Therefore, 
, in other words, angles a and b are complementary by defintion.
So, the right answer is the second choice.
