Mathematics

Find a solution for the equation. Assume that all angles are acute angles.sin A = cos 8A

A. 10° B. 82° C. 8° D. 80°

Solve the system of equations by substitution, if a solution exists.

A. x = , y = 
B. Many solutions
C. x = , y = 
D. No solution

Solve the problem.Let A =  and b =  .Determine if the equation Ax = b is consistent for all possible b1, b2, b3. If the equation is not consistent for all possible b1, b2, b3, give a description of the set of all b for which the equation is consistent (i.e., a condition which must be satisfied by b1, b2, b3 ).

A. Equation is consistent for all b1, b2, b3 satisfying -3b1 + b3 = 0. B. Equation is consistent for all b1, b2, b3 satisfying -b1 + b2 + b3 = 0. C. Equation is consistent for all b1, b2, b3 satisfying 3b1 + 3b2 + b3 = 0. D. Equation is consistent for all possible b1, b2, b3.
