All solutions to the equation 3 cos (5t) + 3 = 2 in the interval from 0 to π will be 0.3821, 0.2462, and 0.8745. Then the correct option is A.

<h3>What is trigonometry?</h3>

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The equation is given below.

3 cos (5t) + 3 = 2

By simplifying the equation, then we have

3 cos 5t = -1

   cos 5t = -1/3

Then the value of t will be

5t = 1.91063, 1.12096, 4.3725

 t = 0.3821, 0.2462, 0.8745

Then the correct option is A.

More about the trigonometry link is given below.
