Tan^2 x+sec^2 x=1 for all values of x. true or false

False 

because tan^2 45 =  1^2 = 1
and sec^2 x =  1/ cos^2 45  =  (sqrt2)^2 = 2

so the sum = 3

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
