Two angles are complementary. One angle measures $\left(4x+1\right)\degree$  and the other measures  $\left(5x-16\right)\degree$  Which of the following would be an equation you could use to solve this problem?

•  $90\degree=\left(20x\right)\degree-17\degree$  

•  $90\degree=\left(4x+1\right)\degree-\left(5x-16\right)\degree$  

•  $90\degree=\left(9x\right)\degree+17\degree$  

•  $90\degree=\left(9x\right)\degree-15\degree$  

Two angles are complementary. One angle measures  $22\degree$  and the other measures  $2x\degree$  .  Solve for x.
