I believe it is 17,400,100. :)
Answer:
Can't do much without a direct question or embedded image.
To solve this we can take two different approaches:
1. We can substitute theta by 30° and evaluate our expression using a calculator:
2. We can use the unitary circle and the fact that
, so we can rewrite our expression as follows:
From our unitary circle we can check that
and
.
Lets replace those values in our expression and simplify:
Either way we can conclude that the correct answer is:
D)8.7
I hope this helps you
length =width +1.25
Area =length ×width
320=w. (w+1.25)
w=18.625
l=19.875
