## hooooooooooope 3 years ago how do you do these? I got 2,3, and 4. But I NEED #1 If you could give me all of them that'd be great

1. hooooooooooope
2. shankvee\

so sin x=8/17. cos x=sqrt(1-xin^2 x)=sqrt(1-64/289)=sqrt(225/289)=-15/17. as it is given cos x is negative. so, sec x=1/cos x=-17/15

3. alexislovesyou5502

have u figured it out yet mister?

4. hooooooooooope

so the overall answer for #1 is ?

5. shankvee\

Did you understand the method or not??

6. hooooooooooope

not really

7. alexislovesyou5502

Look all u have to do is go back to where that person explained it to you and try harder to under stand it!

8. alexislovesyou5502

bye:D

9. shankvee\

Do you know sin^2 x + cos ^2 x=1?

10. hooooooooooope

yeah

11. hooooooooooope

I don't understand what the final answer is for #1. Is it (-17/15) ?

12. shankvee\

Yeah.

13. hooooooooooope

For the rest I have: 2) sin(arctan(1)) 3) 5.196152 4) 8.9644 are those right?

#1 $\cos \Theta$ =-15/17 $\sec \Theta$ =-17/15 #2 $\sin(\tan^{-1} (1)=$ $\sin 45 =$ $\sqrt{2}/2$ #3 $6(1/\sqrt{3})-2(-\sqrt{3}/2)$ $6(\sqrt{3}/3) + \sqrt{3}$ $2\sqrt{3} + \sqrt{3}$ $3\sqrt{3}$ #4 tan 35 = a/10 tan 62 = b/10 a = 0.7002*10 b=1.8807*10 a = 7.002 b = 18.807 Distance between towns is: 18.807-7.002 ans: 11.805

So at the bottom to find the URL i keep doing it but it won't work
