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

anonymous · Answer

45 degrees?

myininaya · Answer

now what is sin(theta)?

myininaya · Answer

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

myininaya · Answer

what measurement is for the opp side of theta?

myininaya · Answer

what is the hyp measurement?

myininaya · Answer

all of this is actually already given

anonymous · Answer

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

anonymous · Answer

and yes, i do realize that now!

myininaya · Answer

right sin(theta)=4/5

myininaya · Answer

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

myininaya · Answer

you know like without a calculator

anonymous · Answer

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

anonymous · Answer

Sorry, degress should be degrees.

anonymous · Answer

alright, thank you!

anonymous · Answer

Your welcome.
