No because you would be dividing the first equation by four, for an example if m=32.5 in the first equation, if you put that into the second equation and divide it by four you won’t get 130 like in the first equation

Answer: 
<u>Step-by-step explanation:</u>
Note the following identities: tan² x = sec²x - 1

tan² x + sec x = 1
(sec² x -1) + sec x = 1
sec² x + sec x - 2 = 0
(sec x + 2)(sec x - 1) = 0
sec x + 2 = 0 sec x - 1 = 0
sec x = -2 sec x = 1
