In geometry, if the angles have the same values of sine and cosine, it implies that the angles are complementary which further means that the sum of their measures should be 90°. With the given expressions for the angles above,

     (x + 11) + (2x + 22) = 90

Simplifying,

    3x + 33 = 90

Further simplification,
    3x = 90 - 33 = 57

The value of x from the equation is 19.

Answer: x = 19

56 is 80 percent of what number
monitta
Let us assume the number to be = x
Then
(80/100) * x = 56
4x/5 = 56
4x = 56 * 5
4x = 280
x = 280/4
  = 70
The value of the unknown number is 70. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems in future without requiring any help from outside. Only thing that needs to be taken care of is the calculation part.
