I have included attachment below
so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2
answer is 336 m^2

Using the fact that cos is 2π-periodic, we have

That is,
for any
and integer
.

We get 2 solutions in the interval [0, 2π] for
and
,

Answer:
8.3
Step-by-step explanation:
Should be D. Let me know if you need more of an explanation.
√2 amount around 1.4
so the best answer is < which means 'less than'
√2 < 1.8
√2 is less than 1.8
