1 + sec^2(x)sin^2(x) = sec^2(x)
This becomes
1+tan^2(x) = sec^2(x) which is an identity
You could
1 + sin^2(x)/cos^2(x) = sec^2(x)
then
cos^2(x) + sin^2(x) = cos^2(x)sec^2(x)
1 = 1
It’s not the same because if you simplify them there going to end up looking different (the answers) And they get a whole different do you denominator a numerator
45,700 would be ur answer
hope i helped:D
Answer:
x =9
Step-by-step explanation:
7x+3 = 6x + 12
x + 3 =12
x = 9
So both angles equal 66*
