Answer:

23.82

Step-by-step explanation:

1) if the coordinates are: A(-5;4), B(0;3), C(4;-1) and D(4;-5), then it is possible to calculate the sides of the given quadretarial;

2) AB=sqrt(26)≈5.1; BC=sqrt(32)≈5.66; CD=4; AD=sqrt(82)≈9.06;

3) the required perimeter is: AB+BC+CD+AD=5.1+5.66+4+9.06=23.82 (units)

Korolek [52]

Answer:

9³

Step-by-step explanation:

We need to find the value of $\dfrac{9^5}{9^2}$ .

We know that,

$\dfrac{x^a}{x^b}=x^{a-b}$

Here, a = 5 and b = 2.

So,

$\dfrac{9^5}{9^2}=9^{5-2}\\\\=9^3$

So, the answer to the given expression is 9³.

Brainliest if correct! Please explain how this is done!

Korvikt [17]

The value of csc C in fraction and in decimal form is as follows:

csc C = 5 / 3

csc C = 1.66666666667

Using trigonometric ratio,

secant A = 1 / cos A = hypotenuse / adjacent

Therefore,

sec A = 5/3

sec A = 1 / cos A

cos A = adjacent / hypotenuse

cos A = 3 / 5

A = cos⁻¹ 0.6

A = 53.1301023542

Therefore,

∠A = 53°

∠B = 90°

∠C = 180 - 143 = 37°

cosec C = 1 / sin C = hypotenuse / opposite

cosec C = 5 / 3
