A) 43,000
10^3 is the same as 10,000
multiply 10,000 by 4.3=43,000
hopes this helps
we are given
S=80
RS=2
we can use tangent formula


now, we can find QR

we will get
...........Answer
If you look at the sine curve,
you'll find the curve passing through x axis,
firat at x=0, and then at x =pi.
hence, after 0, next radian value for which sin x = 0 is x = pi
