Sum of interior angles = 180(n - 2)
in this case n = 5 so 180(5-2) = 180(3) = 540

120 + 120 + x + x + x = 540
3x + 240 = 540
3x = 300
  x = 100

answer
B) 100

Ad libitum [116K]

Answer:

<u>Given</u>

  • Equation 3x - 4y = 8

and

  • Inequality 3x - 4y ≥ 8

<em>See the graphs attached</em>

To draw the graphs follow the rules we described in the previous questions.

  • 1. Identify x-intercept and y-intercept and connect them to have the line.
  • 2. Shade the region above or below the line if this is an inequality.

We see the only difference the expressions have is the equation or inequality symbols.

  • Equation symbol means the graph of the equation is a line.
  • Inequality symbol means the graph of this is a region below the same line, in our case the line is also part of the covered region because it is "≤".

We can state that the inequality includes the line and the region below the same line.

Parallelogram ABCD ​ is a rectangle.
True [87]

Answer:

The value of y is: 7

Step-by-step explanation:

The figure of the rectangle ABCD is attached to the answer.

We are given that Parallelogram ABCD ​ is a rectangle.

AC=6y−1



BD=4y+13


Diagonal BD and AC intersect each other at a point labeled as X.

Also we know that: The two diagonals of a rectangle are equal in length and bisect each other.

i.e. length of AC=BD

Hence 6y-1=4y+13

⇒   6y-4y=13+1

 ⇒  2y=14

  ⇒  y=7

Hence, AC=6×7-1=42-1=41

      BD=4×7+13=41

Hence, the value of y is 7.

The Weight On Earth Compared To Some Rando Planet... pls help
earnstyle [38]

Answer:

if your talking about the earth i dont know because no one have ever compared some random planet and earths weight

Step-by-step explanation:

That’s because the planets weigh different amounts, and therefore the force of gravity is different from planet to planet. For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That’s because Mercury weighs less than Earth, and therefore its gravity would pull less on your body.
