Answer:
i do! can i have brainliest? please? ill give you my thanks
Step-by-step explanation:
24. 43 degrees
25. 90 degrees
26. 47 degrees
I don’t really know what the question was so I assumed you wanted the angle of each?
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
