Answer:

Step-by-step explanation:

Well first you have to find what the total amount of all the interior angles. In Oder to do that you count how many sides the shape has the subtract two from that number. Take the number you get from that and multiply it by 180. That number is total amount of all the interior angles including the angle x. Take the angles you do know and add them together. Take the number you get from that and subtract it from the total amount of all interior angles. The number you get from that is your answer. The answer to this problem is 103.

Find the length of the third side. If necessary, round to the nearest tenth.<br> 6<br> 14

Romashka-Z-Leto [24]

Answer:

≈ 12.6

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the third side, then

x² + 6² = 14²

x² + 36 = 196 ( subtract 36 from both sides )

x² = 160 ( take the square root of both sides )

x = $\sqrt{160}$ ≈ 12.6 ( to the nearest tenth )

Very confusing i know

Answer:

(x + 10)² + (y + 4)² = 232

Step-by-step explanation:

<h3>Given </h3>

Center = (-10, -4)
Point on circle = (4, 2)

The equation of circle

<h3>Solution</h3>

<u>Remember the standard equation of circle:</u>

(x - h)² + (y - k)² = r², where (h, k) is the center and r is radius

h = -10, k = -4

Use distance formula (Pythagorean theorem) to work out the length of the radius. We know that radius is the distance from the center to any point on the circle.

<u>Here we are finding the distance between points (-10, -4) and (4, 2)</u>

r² = (-10 - 4)² + (-4 - 2)²
r² = 14² + 6²
r² = 232

<u>So the equation is:</u>

(x + 10)² + (y + 4)² = 232
