1. Yes a circle is a two-dimensional figure. It lies in the plane, which is basically a flat piece of paper that doesn't bend or curve, and the paper extends infinitely in all directions.

2. A circle is not a polygon. A polygon has finitely many straight line segments that glue together to form an enclosed figure. Think of fencing in an area with straight fence portions.

3. Yes this is what makes a circle. Every point on the circle is the same distance from the center. We say these points on the circle are equidistant from the center.

Answer:

Is a circle a two d figure?

YES. It is a flat figure.

Is a circle a polygon?

NO, because it does not have 4 straight sides.

Is every point in a circle the same distance from the center?

YES. All points in a circle are equidistant from the center (they are all equal)

29. Determine the value of x. abc X + 42° 147° 2x

suter [353]

Answer:

x=35

Step-by-step explanation:

180-147=33 (angles in a straight line)

33+3x+42=180 (angles in a triangle)

3x+42=147

147-42=105

Identify the angle measures of PQRS.

kap26 [50]

The opposite angles of an inscribe quadrilateral are supplementary.

angle P + angle R = 180
6x + 7 + 12x + 11 = 180
18x + 18 = 180
18x = 162
x = 9

Now we will substitute in the value of x to find angle P and R.

angle P = 6(9)+7 = 61
angle R = 12(9)+11 = 119

Now we will find the value of y.

angle Q + angle S = 180
10y + 7 + 3(3y + 7) = 180
10y + 7 + 9y + 21 = 180
19y + 28 = 180
19y = 152
y = 8

Now substitute in the value of y to find angle Q and S.

angle Q = 10(8)+7 = 87
angle S = 3(3*8+7) = 93

Hope this helps :)

Miquel created the table below to show how he uses the money he earns at work

lara [203]

Complete Question with table is attached

Answer:

Miguel will save money of $90 if he earns $120.00

Step-by-step explanation:

The figure attached clearly shows the ratio of his earnings and savings. We have to find what would be the savings amount if he earn $120.00. So, first we have to calculate the percentage of ratio of his earnings and savings. As per the data given in the figure,

If he earns $10.00, he saves $7.50, calculate %amount he saves as below,

$\frac{\$ 7.50}{\$ 10.00} \times 100=0.075 \times 100=75 \%$

Likewise, calculate for all given data. If he earns $50.00 then he saves $37.50

$\frac{\$ 37.50}{\$ 50.00} \times 100=0.75 \times 100=75 \%$

If he earns $150.00 and save $112.50,

$\frac{\$ 112.50}{\$ 150.00} \times 100=0.75 \times 100=75 \%$

So, from all above, it clearly tells that Miguel saves 75% of amount from his earnings. Now, given earnings as $120.00. By finding 75% of $120.00, we can find his savings in that amount. So,

$\frac{75}{100} \times \$ 120=0.75 \times 120=\$ 90$
