Question

Solve: 2sec(x) + 5 = 9

Which equation is equivalent to the given
equation?
cos(x) =1/2
cos(x) = -2
sin(x) = 1/2
sin(x) = -2

Answer 1

Answer: cos(x)= 1/2 is correct

Step-by-step explanation: just got the answer right

Answer 2

`\cos(x)=(1)/(2)`

Explanation:

`2\sec(x)+5=9\\\\2\sec(x)=4\\\\\sec(x)=2\\\\(1)/(\sec(x))=(1)/(2)\\ \\\cos(x)=(1)/(2)`

Thus, the first option is correct
