The correct explanation for the student's error is: (C) The two angles do not equal 180°. They are vertical angles, so 2x+6=60
Vertical angles are pairs of angles formed when two lines intersect. These angles are opposite each other and have equal measures. However, the student incorrectly assumed that the vertical angles were supplementary angles (adding up to 180°).
As a result, they set up the equation as 2x + 6 + 60 = 180, which does not apply to vertical angles. This is why option C explains the error by stating that the two angles are vertical angles, and the correct equation should be 2x + 6 = 60.
To solve the correct equation for 'x', which is 2x + 6 = 60, follow these steps:
Start with the equation: 2x + 6 = 60Subtract six from both sides of the equation: 2x = 54Divide both sides by 2: x = 27The correct solution is x = 27, which means that the value of 'x' that satisfies the equation 2x + 6 = 60 is 27. This correctly reflects the measure of the angle within the given context.
In summary, the student's error stemmed from misunderstanding the nature of vertical angles and incorrectly assuming that they were supplementary angles. By recognizing the correct characteristics of vertical angles and applying the appropriate equation, the solution can be accurately determined as x = 27.

The percentage of water in fresh mushrooms is 10 percent.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, from 22 kilograms of fresh mushrooms, 2.5 kilograms of dry mushrooms are obtained, containing 12% water.
Let x% of water in fresh mushrooms.
Here, x% of 22 = (100-12)% of 2.5
x/100 ×22 = 88% of 2.5
22x/100= 88/100 ×2.5
22x=88×2.5
x=4×2.5
x=10%
Therefore, the percentage of water in fresh mushrooms is 10 percent.

A city just opened a new playground for children in the community. An image of the land that the playground is on is shown.
A polygon with a horizontal top side labeled 45 yards. The left vertical side is 20 yards. There is a dashed vertical line segment drawn from the right vertex of the top to the bottom right vertex. There is a dashed horizontal line from the bottom left vertex to the dashed vertical, leaving the length from that intersection to the bottom right vertex as 10 yards. There is another dashed horizontal line that comes from the vertex on the right that intersects the vertical dashed line, and it is labeled 12 yards.
What is the area of the playground?
900 square yards
855 square yards
1,710 square yards
1,305 square yards
Answer:
By answering the presented question, we may conclude that Therefore rectangle 855 square yards is the closest response choice.
What is rectangle?
In Euclidean geometry, a rectangle is a parallelogram with four small angles. It may also be defined as a fundamental rule hexagon or one in which all of the angles are equal. Another alternative for the parallelogram is a straight angle. Four of the vertices of a square are the same length. A quadrilateral with four 90° angle vertices and equal parallel sides has a rectangle-shaped cross section. As a result, it is also known as a "equirectangular rectangle." A rectangle is sometimes referred to as a parallelogram due to the equal and parallel dimensions of its two sides.
The rectangle has a 20-yard base and a 10-yard height, hence its area is:
200 square yards = 20 yards x 10 yards
The triangle on the left has a 20-yard base and a 45-yard height (since the top side of the polygon is indicated as 45 yards), hence its area is:
450 square yards = 1/2 x 20 yards x 45 yards
210 square yards = 1/2 x 12 yards x 35 yards
As a result, the total playground area is:
860 square yards = 200 square yards plus 450 square yards plus 210 square yards
Therefore 855 square yards is the closest response choice.

vertical

angles.
∠6 and ∠8 are ___ angles. (same options as first one)
∠1 and ∠5 are ___ angles. (same options as first one)
Answer:
∠1 and ∠2 are supplementary angles.
∠6 and ∠8 are vertical angles
∠1 and ∠5 are corresponding angles.
Step-by-step explanation:
∠1 and ∠2 lie on a straight line which will always add up to 180 degrees or supplementary.
∠6 and ∠8 lie opposite each other on the transversal (intersecting line) and are equal.
<1 and <2 are Supplementary angles
<1 and <5 are Corresponding angles
<6 and <8 are Vertical angles
Given that d II e
when a transversal intersects two parallel lines the following conditions are true:
Supplementary angles are those angles when the sum of two angles is equal to 180 degrees. Since <1 and <2 are on either side of the transversal their sum is equal to 180 degrees hence why it's a supplementary angle.
Vertical angles form 4 angles when a line intersects them and the two angles are opposite to each other. In this case <6 and <8 are opposite each other hence why they are vertical angles.
Corresponding angles are the angles that are in the same position on each of the parallel lines and on the same side of the transversal. In this case both <1 and <5 are on the same side of the transversal on each of the parallel lines hence why they are corresponding angles
