Option A

Opposite angles in a cyclic quadrilateral add up to 180°

So

her

x and 133 are opposite angles

  • x+133=180
  • x=180-133
  • x=47°

Part A is done after part B

Answer:

<u>Quadrilateral</u>: A two-dimensional shape with 4 straight sides and 4 interior angles.

<u>Cyclic Quadrilateral</u>:  A quadrilateral drawn inside a circle where every vertex of the quadrilateral touches the circumference of the circle.

We know that opposite angles in a cyclic quadrilateral are supplementary, which means their sum is 180°

Therefore:

⇒ x + 133° = 180°

⇒ x = 180° - 133°

⇒ x = 47°

Opposite angles in a cyclic quadrilateral add up to 180°

Mohammad would like to graph the line that represents the total number of baseball cards he will
Marina CMI [18]

Answer:

To best show this information, the scale for the T-axis of his graph should go from 0 to at least 60.

To best show this information, the scale for the m-axis of his graph should go from 0 to at least 12.

Step-by-step explanation:

Mohammad will have collected T cards after m months, given that he buys 5 cards each month and he started with no cards.

The relationship describing this situation is

T=5m

When m=6, then T=5\cdot 6=30 cards.

When m=12, then T=5\cdot 12=60 cards.

To best show this information, the scale for the T-axis of his graph should go from 0 to at least 60.

To best show this information, the scale for the m-axis of his graph should go from 0 to at least 12.

The area of a square is given by x?, where x is the length
Rudik [331]

Answer:

Step-by-step explanation:

If she doubles the area of her lot, it should be 2x^2.

But how do you get that?

The answer is that the sides have now increased to √2x

How did I get that, and why did I choose it?

  • The formula for a square's area is s^2
  • If you want to double the area, it will be 2 s^2.  Now what?
  • Take the square root of 2s^2 which is √(2s^2).
  • What that means is the side is now √2 s

I remember CUP -- concave up positive.  Here we have a leading coefficient that's negative, so the cup is upside down, the parabola opens down, an arch not a bowl.
