Three copies of a triangle were rotated and positioned as shown. Which statement is always true about the angles in the figure?a. Angle a and angle b form a right angle
b. Angle a, angle b, and angle c, form a straight angle.
c. angle a, angle b, and angle c from a acute angle.
d. Angle a and angle c form a right angle

Answers

Answer 1

Answer:

If the above image is the supposed image for this problem, then,

B. Angle A, Angle B, and Angle C, form a straight angle.

A straight angle is 180°. C A B found in the middle of the picture forms the 180° straight angle.

Right angle is an angle which is equivalent to 90°
Acute angle is an angle which has less than 90°

As I can observe, the three triangles have two equal sides and two equal angles. These triangles are identified as isosceles triangles.

Which two integers is 3
12 between?

Answers

To determine which two integers 3 is between, we need to find the closest integers that are smaller and larger than 3.

1. Find the largest integer that is smaller than 3:

- The largest integer smaller than 3 is 2.

2. Find the smallest integer that is larger than 3:

- The smallest integer larger than 3 is 4.

Therefore, 3 is between the integers 2 and 4.

I hope this explanation clarifies the integers that 3 is between. Let me know if you have any further questions.

What is the elapsed time between 2:16 AM and 8:10 PM

Answers

So we wan't to know how much time has passed from 2:16 AM till 8:10 PM. If we know that one day has 24 hours and that AM and PM are two 12 hour periods we can say the following: 2:16 AM is 2:16 h in the 24 hour cycle. and 8:10 PM is 20:10 h in the 24 hour cycle. so from 2:16 hours to 20:10 hours there is a time interval of 17 hours and 54 minutes.

17 hours and 54 minutes

What is the radius of a circle with center (2,1) and containing point (0,1)

Answers

Answer:

The radius is 2 or The simplified radius is 4 ( if needed).

Step-by-step explanation:

- The equation of a circle is:

$(x-h)^2+(y-k)^2=r^2$ where the center is $(h,k)$ , the point as $(x,y)$ and the radius $r^2$ .

-Put both the center and the point onto that equation:

$(0-2)^2+(1-1)^2=r^2$

-Then, solve them up:

$(0-2)^2+(1-1)^2 =r^2$

$(-2)^2+0=r^2$

$4 + 0=r^2$

$4 = r^2$

$√(4) =√(r^2)$

$2=r$

Find the perimeter of a quadrilateral with vertices at C (−1, 2), D (−2, −1), E (2, −2), and F (1, 1). Round your answer to the nearest hundredth when necessary.

Answers

To get the perimeter of the quadrilateral, the distance formula can be used. We simply have to subtract the y coordinate of one point to another and the same for the x coordinate. The square root of the sum of the squares of the difference is the distance.The results can then be added to get the perimeter. So,
CF = sqrt ( (2-(-1))^2 + (-1-(-2))^2 ) = sqrt(10)
FE = sqrt ( (-2-1)^2 + (2-1)^2 ) = sqrt(10)
ED = sqrt ( (-1-(-2))^2 + (-2-2)^2 ) = sqrt(17)
DC = sqrt ( (2-(-1)^2 + (-1-(-2))^2 ) = sqrt(10)

P = CF + FE + ED + DC = sqrt(10) + sqrt(10) + sqrt(17) + sqrt(10) = 13.61

Answer: The answer is 12.68 units.
