Question

place the answer in scentific notation, when appropriate and simplify the units.

(1.33)sin35.0=(1.50)sinθ

35.0 is in degrees

Answer 1

(1.33)sin35.0/(1.50)=sin theta

Answer 2

sin 35 =0.573576436

Answer 3

sin theta= 0.573576436*1.33/1.5=0.508571106
theta=30.57 degrees

Answer 4

thanks i got it

Answer 6

And the answer had only three significant figures, right? I'm just saying this in case someone looks through closed questions or finds it through Google. So, if the calculations were right, the answer should be \(30.6^\circ\) with proper significant figures.

For significant figures, all you need to know is
1. how to count them, and
2. how you choose how many after addition/subtraction or multiplication/division.
