3)first you count the sides
There are 8 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(8-2)*180
=6*180=1080

To find the measure of one interior angles divide the answer by the number of sides
900/8=112.5



4)first you count the sides
There are 7 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(7-2)*180
=5*180=900

To find the measure of one interior angles divide the answer by the number of sides
900/7= 128.57

den301095 [7]

Answer:

Ordered

Step-by-step explanation:

The ordered pair is the location of a point on the coordinate plane and contains the x coordinate and y coordinate

An ordered pair tells you the location of a point by relating the point's location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair). In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate.

WILL GIVE BRAINLIEST!! ABC is a triangle. Find the size of the largest angle in the triangle. Give your answer in degrees correc
zubka84 [21]

Answer:

  • 98.2°

Step-by-step explanation:

The largest angle is opposite to the largest side.

Since the largest side is BC, the largest angle is A.

<u>Work out the angle measure using the law of cosines:</u>

  • cos ∠A = (b² + c² - a²)/(2bc)
  • cos ∠A = (3² + 7² - 8²)/(2*3*7)
  • cos ∠A = -0.14286
  • m∠A = arccos (-0.14286)
  • m∠A = 98.2°

I need help using the distance formula to find the perimeter of a parallelogram JKLM
krok68 [10]

let's first notice the distance of LM, is a vertical line, so we can just do a plain subtraction, -1.6 -(-0.4) => -1.6 +0.4 => -1.2 and the distance is just |-1.2| or 1.2.

let's check KJ, another vertica line, -1.7 - (-0.5) => -1.7 + 0.5 => -1.2 => |-1.2| = > 1.2.

so LM = KJ, and both are vertical, meaning we have a parallelogram, which means KL = JM.

so let's just find say... KL and  her twin will be the same.


\bf ~~~~~~~~~~~~\textit{distance between 2 points}&#10;\\\\&#10;K(\stackrel{x_1}{-0.5}~,~\stackrel{y_1}{-1.7})\qquad&#10;L(\stackrel{x_2}{-0.7}~,~\stackrel{y_2}{-0.4})~\hspace{3.5em}&#10;d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}


\bf KL=\sqrt{[-0.7-(-0.5)]^2+[-0.4-(-1.7)]^2}&#10;\\\\\\&#10;KL=\sqrt{(-0.7+0.5)^2+(-0.4+1.7)^2}\implies KL=\sqrt{(-0.2)^2+1.3^2}&#10;\\\\\\&#10;KL=\sqrt{0.04+1.69}\implies KL=\sqrt{1.73}\implies KL\approx 1.315&#10;\\\\[-0.35em]&#10;\rule{34em}{0.25pt}\\\\&#10;\stackrel{\textit{perimeter}}{\stackrel{LM}{1.2}+\stackrel{KJ}{1.2}+\stackrel{KL}{1.315}+\stackrel{JM}{1.315}}\implies 5.03
