Answer:

x = 9

Step-by-step explanation:

The sum of the 4 angles in a quadrilateral = 360°

Sum the given angles and equate to 360

90 + 109 + 9x - 5 + 85 = 360, that is

9x + 279 = 360 ( subtract 279 from both sides )

9x = 81 ( divide both sides by 9 )

x = 9

Burka [1]

By subtracting the water poured into the first two beakers from the available water we conclude that the water left for the third beaker is 0.9 liters.

<h3>How to find the water left for the third beaker</h3>

In this question we know that Karen has 3 liters of water and poured 0.7 liters into the <em>first</em> beaker, 1.4 liters into the <em>second</em> beaker and we can determine the water left for the <em>third</em> beaker by subtracted the water poured into the <em>first two</em> beakers from the available water. The available volume is:

V = 3 L - 0.7 L - 1.4 L

V = 0.9 L

By subtracting the water poured into the first two beakers from the available water we conclude that the water left for the third beaker is 0.9 liters.
