Numerical Answers Expected!

Answer 2

wht is your ans?

Answer 3

You will use here:

\[\sin(\theta) = \frac{Perpendicular}{Hypotenuse}\]

Answer 4

So:

\[\large \color{green}{\sin(60^{\circ}) = \frac{x}{132}}\]

Solve this for x..

Answer 5

so u times them

Answer 6

I had got it wrong. My answer was 114.31

Answer 7

wht is the correct or given ans?

Answer 8

Just multiply value of sin(60) with 132, you will have x..

Answer 9

thats exactly my answer too @marylou004

Answer 10

Yep.. Right..

Answer 11
