[10 points] True or False? Circle your answer and provide a justification for your choice. (a) T F: If A is invertible, then so is the corresponding cofactor matrix C. (b) T F: For any u, v, w ∈ R 3 , u · (v × w) = v · (w × u) = w · (u × v). (c) T F: If 0 is an eigenvalue of an n × n matrix A, then C(A) = R n . (d) T F: If λ is an eigenvalue of a square matrix A, then every element in N(A − λI) is an eigenvector of A with eigenvalue λ. (e) T F: If λ is an eigenvalue of a square matrix A, then λ is an eigenvalue of AT as well

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
