Answer:

The third angle is 50°

Step-by-step explanation:

In a triangle, all the angles must add up to 180° such that:

[tex]180= a+b+c[/tex]  where a , b, and c are all angles

Since we know that two of the angles are 57° and 73°, we can subtract them from 180° to find the third angle.

Using the above equation, we can rearrange it to solve for the missing value:

180°= a + b + c

180°=57°+ 73° +c                          Substitute the angles in for any 2 variables

180°- 57°-73°= c                    Rearrange the equation to solve for last variable

50°= c

The third angle is 50°

Answer:

(x - 3)² + (y - 2)² = 16

Step-by-step explanation:

The center of the circle is (3, 2).

The radius of the circle is 4.

(x - 3)² + (y - 2)² = 4²

Answer: (x - 3)² + (y - 2)² = 16

The complete equation of this circle​ with center (3, 2) and radius 4 units is

(x - 3)² + (y - 2)² = 4²

Used the concept of the equation of the circle which stated that,

The standard form of the equation of a circle is,

(x - h)² + (y - k)² = r²

Where, (h, k) is the center of the circle and 'r' is the radius of the circle.

Given that,

The center of the circle is (3, 2).

And, The radius of the circle is 4.

Here, (h, k) = (3, 2)

And, r = 4

Substitute all the values in the standard form of the equation of a circle,

(x - 3)² + (y - 2)² = 4²

Therefore, the equation of a circle,

(x - 3)² + (y - 2)² = 16

Answer:

positive slope is shown by the graph

Answer:

v = 87

Step-by-step explanation:

the angle v+39 lies on a straight line. so substract v+39 from 180 to get the interior angle for that side.

afterwards, knowing that the sum of interior angles of a triangle = 180, form an equation with all the angles and solve for v

Answer:

20

Step-by-step explanation:

A data is given and the mean of data is 19.6 .The data is ,

12 , 16 , 22 , x , 28 .

We know that the mean is sum of observations divided by Total number of observations . So that ,

⇒ 12 + 16 + 22 + x + 28/ 5 = 19.6

⇒ 78+x/5 = 19.6

⇒ 19.6 × 5 = 78 + x

⇒ 78 + x = 98

⇒ x = 98 - 78

⇒ x = 20

Answer:

m = 6[tex]\sqrt{3}[/tex] , n = 6

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle and exact values

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , sin30° = [tex]\frac{1}{2}[/tex] , then

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{m}{12}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2m = 12[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

m = 6[tex]\sqrt{3}[/tex]

and

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{n}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2n = 12 ( divide both sides by 2 )

Answer:

5.6

Step-by-step explanation:

Given :

Quality rating for 8 movies :

5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, 5.2

Let rating for the 9th movie = x

Average quality rating olfor the 9 movies = 6.4

To find x :

Sum of all ratings / number of ratings = 6.4

(5.6 + 7.9 + 7.0 + 5.9 + 7.8 + 6.2 + 6.4 + 5.2 + x) / 9 = 6.4

(52 + x) / 9 = 6.4

52 + x = 57.6

x = 57.6 - 52

x = 5.6
