Answer:
65x
Step-by-step explanation:
Observe que estos son terminos similares... por lo que podemos simplemente sumarlos y restarlos. Entonces obtenemos:
25x + 12x + 31x - 8x + 5x
= 37x + 31x - 8x + 5x
= 68x - 8x + 5x
= 60x + 5x
= 65x
as a decimal it would be 11.5
and as a fraction it would be 23/2
so none of those answers?
It would be -4x+(-12)=12 good luck
I believe 60 degree is your answer
I hope this helps you
✔cos^2A+sin^2A=1
✔1-cos^2A=sin^2A
✔cos2A=cos^2A-sin^2A
✔sin2A=2.sinA.cosA
secA=1/cosA
tgA=sinA/cosA
sin^2A/1/cos^2A-sin^2A/cos^2A
sin^2A.cos^2A/cos2A
2.sin^2A.cos^2A/cos2A
sin2A.2.sin2A/cos2A
tg2A.2.sin2A
