25cos^x + 25 sin^x=​

Answer»

ANSWER:

25

Step-by-step explanation:

25cos^2x+25sin^2×

25cos^2x+25sin^2×=25(cos^2x+sin^2x)

25cos^2x+25sin^2×=25(cos^2x+sin^2x)[sin^2+cos^2=1]...Trignometric identity

25cos^2x+25sin^2×=25(cos^2x+sin^2x)[sin^2+cos^2=1]...Trignometric identity=25(1)

25cos^2x+25sin^2×=25(cos^2x+sin^2x)[sin^2+cos^2=1]...Trignometric identity

=25(1)=25

25 is your answer.
