4.32 is the answer to ur question if u need to round then it would be 5
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
.35 is the answer because when you write it as a fraction
7/20we know that 20 equals 100we get 100by multiplying 20 by 5 do you just multiply 7by5 which equals 35 over 100 which equals .35.please follow me on brainly
