MARKING BRAINLIEST For what value of x makes the polygon below a rhombus?

Mathematics
1 answer:
mamaluj [8]3 years ago
4 0

Answer:

x=7

Step-by-step explanation:

In order for this figure to be a rhombus, the interior sides have to  add up to 180, and the angle not given by an expression has to be 90.

90+8x+7+3x+6=180

Combine like terms

90+11x+13=180

103+11x=180

Subtract 103 from both sides

11x=77

Divide both sides by 11

x=7

The graph of an equation is shown below:
Ganezh [65]

Answer:

(1, 3)

Step-by-step explanation:

The first number of each pair is the x-coordinate, the horizontal location of the point.

The end points of the graphed line segment are (1, 3) and (-3, -2). It looks like the answer choices are intended to see if you can tell what order the coordinates are expressed in.

The appropriate choice is (1, 3), the upper right end point.
