Answer:
<h3>6</h3>
Step-by-step explanation:
Given the expression sin(9z − 1) = cos(6z + 1), for 0 < z ≤ 90, we are to find z
Note that sin theta = cos(90-thetsa)
sin(9z − 1) = cos(6z + 1)
cos (90 - (9z-1)) = cos(6z + 1)
cos (90 - 9z+1)) = cos(6z + 1)
cos (91-9z) = cos(6z + 1)
Cos will cancel out to have;
91-9z = 6z+1
-9z - 6z = 1-91
-15z = -90
z = 90/15
z = 6
Hence the value of z is 6

Answer:
3x - 27 = 51
x equals 26
Step-by-step explanation:
3(dollars) times x(number of shirts sold). Then you subtract the amount she spent on supplies($27) and you get 51, the total profits she made.
