Cos(3x) = 1 1. Using an appropriate inverse trigonometric expression, write an equation that defines the value of 3x

2. Solve this equation to find all possible values of the angle 3x

3. Use algebra to find all values of x between 0 and 2pi that satisfy this equation

Step-by-step explanation:

cos(3x) = 1

3x = 0 + 2kπ

x = 0 + 2kπ/3

x = 0, 2π/3, 4π/3, 2π

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the answer is a if my teacher taught me correct
