Answer:

A = 4m*9m = 36m^2

Step-by-step explanation:

After a quick online search, I've found that the image of the parallelogram is the one that can be seen below.

In the image we can see a parallelogram with sides:

S1 =  9m (the base)

S2 = 5m

And an altitude H = 4m

For a parallelogram, the area is given by the base times the altitude

In this case, we know that the base is b = 9m, and the altitude is H = 4m

Then the area of the parallelogram show is:

A = 4m*9m = 36m^2

If sec theta = - √30 / 3, find cos theta.<br> if sin(-theta) = -0.97, find cos (π/2 - theta).
Cloud [144]

Step-by-step explanation:

\cos \theta  =  \frac{1}{ \sec\theta }  =  -  \frac{3}{ \sqrt{30} }  =  -  \frac{3 \sqrt{30} }{30}   =  -  \frac{ \sqrt{30} }{10}

\cos( \frac{\pi}{2} -  \theta )=  \cos \frac{\pi}{2}  \cos \theta  +   \sin \frac{\pi}{2}  \sin \theta

Note that

\sin( - \theta) =  -  \sin \theta

\cos \frac{\pi}{2}  = 0 \:  \:  \:  \:  \:  \sin \frac{\pi}{2}  = 1

Therefore,

\cos( \frac{\pi}{2} -  \theta )  = 0.97
