Given   sin²a + cos²a = 1  

and

              \frac{1}{cos^{2} a}  \\= \frac{sin^2a+cos^2a}{cos^2a}  \\                         \\\\ = \frac{sin^2a}{cos^2a} +\frac{cos^2a}{cos^2a}

A/4 - 5/6 = 1/2<br> a/4 - 5/6 = 1/2 help
alexgriva [62]

Answer:

a = 16/3 or 5 1/3 or 5.33...

Step-by-step explanation:

to find a you must first make all of the denominators the same

you must find 4 6 and 2s CGF

and that is 12

so multiply a/4 by 3/3 and get 3a/12

then multiply 5/6 by 2/2 and get 10/12

and lastly multiply 1/2 by 6/6 and get 6/12

at this point you can set the equation up like this

3a/12 - 10/12 = 6/12

but then you can multiply everything by 12

3a - 10 = 6

and then solve

add 10 to both sides

3a = 16

then divide 3 on each side

a = 16/3 or 5 1/3 or 5.33...
