Me! if 0 < f ≤ 90 and cos(22f - 1) = sin(7f + 4), what is the value of f?
a- f =3
b- f =4
c- f=5
d- f=6

Step-by-step explanation:

A

Step-by-step explanation:

We know that x is an angle where 0<x<=90

so from the above equation

   -----(i)

and  -----(ii)

so we can find the value of f by solving these two equations.

by putting value of x from (i) into (ii)

So option A is the correct answer.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
