Step-by-step explanation:

Step 1: Define

f(x) = 3sinx°

f(22) is x = 22

Step 2: Evaluate

Substitute in x:                                                                                               f(22) = 3sin22°Trig:                                                                                                                 f(22) = 3(0.374607)Multiply:                                                                                                           f(22) = 1.12382Round:                                                                                                            f(22) = 1.12

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
