Question

Solve the equation 3tan(2x+15)=4 for 0 14 years ago

Answer 1

3tan(2x+15)=4
tan(2x+15)=4/3
2x+15=arctan(4/3)
2x =arctan(4/3)-15
x =(arctan(4/3)-15)/2

Answer 2

Pick the value that is between 0 and 180

Answer 3

Is that the only value?

Answer 4

There are multiple values because the equation is ______
I forgot the word but when you graph a cos and sin you just see it go on and on and on. So you can have multiple values for x but they want you to find it for a very specific spot between 0 and 180
