The area of the square is 4 × 4 which equals 16cm^2. The area of a circle is π × radius^2, so using 3.14 as pi we can say that (3.14 × 16)/4 is the area of the quarter circle. This comes to 12.56, so added to 16 you get 28.56cm^2 as your answer, which can be rounded to 28.6cm^2. I hope this helps!

What relationship do the ratios of sin x° and cos y° share?
Assoli18 [71]

Answer:

sin(x) = cos(y)

Step-by-step explanation:

Let's figure out what sin(x) and cos(y) are before we figure out the relationship.

Sine is opposite / hypotenuse. Here, the opposite side to angle x is 12 and the hypotenuse is 13. So, sin(x) = 12/13.

Cosine is adjacent / hypotenuse. Here, the adjacent side of angle y is 12 and the hypotenuse is 13. So, cos(y) = 12/13.

Now we can see the relationship: sin(x) = cos(y)

In fact, for any right triangle with angles 90°, α°, and β°, where α and β can be any angle degree that add up to 90, the following relationships are true:

sin(α) = cos(β)

and

sin(β) = cos(α)

Simultaneous equations <br>5x + 3y= 31<br>2x + y = 12 <br><br>a. find for x​<br>b. find for y
Anna007 [38]

Answer:

x=5

y=2

Step-by-step explanation:

5x + 3y= 31

-6x - 3y = -36  (multiple  by -3)

 

-x=-5

x=5

2(5)+y=12   or         25 + 3y= 31

10+y=12                  3y=6

y=2                          y=2
