## Jessica0089 one year ago can someone please please check my work? Will fan and give medal! sin(tan^-1(4/3)) a. the hypotenuse would be 5 b. Angle theta is the angle whose tangent is 4/3 . Find the sine of angle theta. for that i have a hard time understanding

2. Jessica0089

45 degrees?

3. myininaya

now what is sin(theta)?

4. myininaya

recall sin(theta)=opp side of theta/hyp

5. myininaya

what measurement is for the opp side of theta?

6. myininaya

what is the hyp measurement?

7. myininaya

all of this is actually already given

8. Jessica0089

sine theta here is 4/5 and my hyp=5

9. Jessica0089

and yes, i do realize that now!

10. myininaya

right sin(theta)=4/5

11. myininaya

they are basically giving you a way to evaluate sin(tan^-1(4/3))

12. myininaya

you know like without a calculator

13. robtobey

a. is correct. The actual angle value in degress is not necessary. The sine is 4 over 5.

14. robtobey

Sorry, degress should be degrees.

15. Jessica0089

alright, thank you!
