d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\
d=\sqrt{(-5-(-9))^2+(-5-(-2))^2}\\\\
d=\sqrt{16+9}\\\\
d=\sqrt{25}\\\\
d=5

Fudgin [204]

Answer:

128.57 degrees per each interior angle

Step-by-step explanation:

For interior angles of regular polygons, all you have to do is add 180 degrees to the sum for each side added. For example, from triangle to quadrilateral, you would do 180 + 180 to get 360. Then from quadrilateral to pentagon, you would do 360 + 180 = 540. Do that all the way up to a heptagon and you get a sum of 900 degrees. 900 divided by seven angles will get you <u>128.57 degrees per interior angle.</u>

How much weight does the women in the video lose in a year? 80 pounds 90 pounds 50 pounds 20 pounds
Alex Ar [27]

Medical practitioners recommend losing around 365 pounds or 730 pounds per year.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Medical practitioners recommend losing around 1–2 pounds (0.5–0.9 kg) per week.

Hence for a year:

Amount of weight loss = (1 * 365) or (2 * 365)

Medical practitioners recommend losing around 365 pounds or 730 pounds per year.

All the pictures are in order for every question
ivanzaharov [21]

Answer:

  1. C.) obtuse triangle
  2. 39°
  3. 167°
  4. D.) 111°

Step-by-step explanation:

1. The sum of angles in a triangle is 180°. The sum of the given angles is less than 90°, so the remaining angle must be more than 90°. When the largest angle is more than 90°, it is an obtuse angle. A triangle with an obtuse angle is classified as obtuse.

__

2. The sum of the interior angles is 180°, so we have ...

  x° +39° +102° = 180°

  x° = 39° . . . . . . . . . . . subtract 141°

__

3. The third interior angle is the supplement to the sum of the given interior angles. Likewise, x° is the supplement to the third interior angle, so its value is the same as the sum of the two given interior angles. (The rule is often stated as "an exterior angle is equal to the sum of the remote interior angles.")

  x° = 130° +37°

  x° = 167°

__

4. Same deal as problem 3:

  x° = 75° +36°

  x° = 111°

73x+5y=7

73*4+5*(-1)=287

287\neq 7

____________________________

175x−3y=17

175*4-3*(-1)=703

17\neq 703
