Answer:
The length of the inclined plane AC = x = 8.6 ft
Step-by-step explanation:
Height = AB = 5 ft
BC = 7 ft
Now length of inclined plane AC = x
Apply pythagores theorem for ΔABC
x = 8.6 ft
Therefore the length of the inclined plane AC = x = 8.6 ft
Recall
or, $\csc^2\theta-\cot^2\theta=1 \implies (\csc\theta+\cot\theta)(\csc\theta-\cot\theta)=1$
Now, $\cot \theta - \csc \theta = P$
$\implies (-P)(\csc\theta+\cot\theta)=1$
or $(\csc\theta+\cot\theta)=-\frac{1}{P}$

D
Step-by-step explanation:
Non of the other answers have negatives in them. And you would solve with multipliation.
Answer:
Step-by-step explanation:
Area of parallelogram = Base x height
If two parallelograms are similar, then their corresponding sides are proportional.
That means,
Hence,
