The length of the 135˚ arc below is 15/4 π. Find the radius of the circle. Please explain the answer.

Answers

Answer 1

Answer:

The radius of the arc is 5

Step-by-step explanation:

An arc is a part of the circumference of a circle that has been cut out. It can be best understood as an incomplete circle. The length of the arc is how long the arc is.

The formula relating how long the arc is with its radius is

length of arc = [tex]\frac{\theta}{360} \times 2 \pi R[/tex]

where R is the radius we are looking for.

Θ = 135 which can be seen as the arc angle

[tex]R =\frac{l \times 360}{\theta \times 2 \pi} =\frac{(15 \pi /4) \times 360 }{135 \times 2 \pi}=5[/tex]

The radius of the arc = 5

25x13=325

1,235-325=910

910/13=70 :)

What is m∠A and what is m∠B?

Answers

Answer:

m∠A = 79°m∠B = 112°

Step-by-step explanation:

We have cyclic quadrilateral as all vertexes are on the circle.

As per property of cyclic quadrilateral, each pair of opposite angles are supplementary.

As we know supplementary angles add up to 180°.

m∠A + m∠C = 180° ⇒ m∠A = 180° - 101° = 79°m∠B + m∠D = 180° ⇒m∠B =  180° - 68° = 112°

Answers

Answer:  133

=============================================================

Explanation:

The quickest way to get this answer is to add the angles given to get 87+46 = 133

This is through the use of the remote interior angle theorem.

Note how the angles 87 and 46 are interior, or inside the triangle. And also, they are not adjacent to the exterior angle we want to find. So that's where the "remote" portion comes in.

----------------

The slightly longer method involves letting x be the measure of the missing interior angle of the triangle.

The three interior angles add to 180

87+46+x = 180

133+x = 180

x = 180 - 133

x = 47

The missing interior angle of the triangle is 47 degrees.

Angle 1 is adjacent and supplementary to this 47 degree angle, so,

(angle1)+(47) = 180

angle1 = 180-47

angle1 = 133 degrees

This example helps confirm that the remote interior angle theorem is correct.

Hey there!

The answer is 6:54

The time on the clock shows 6:20, because the hour hand is after the 6, and the minute hand is on the 4 (which we multiply by 5 to get the minutes).

If it takes her 8 minutes to walk to the bus, 10 to pack lunch, and 16 to get dressed, that's a total of 8 + 10 + 16 minutes, or 34 minutes.

So, we add that to the minutes, so 20 + 34 = 54, therefore the time is 6:54 when she arrives.

used to find the cost, in dollars, of each video game (v) and each DVD (d) at the store?

Answers

Answer:

I think that the Linear system of equations can be used to find the cost.

Step-by-step explanation:

Answer:

2v + 1d = 105

and

1v + 4d = 80

Step-by-step explanation:

ken : 2v + 1d = 105

Jerome : 1v + 4d = 80

1v + 4d = 80 Try to get a video games by its self

   - 4d    -4d

1v = 80 - 4d    

Plug into kens equation..

2(80 -4d) + 1d = 105

160 - 8d + 1d = 105

-160                 -160

-7d = -55

/-7        /-7

d = 7.86 (rounded)

Plug into Jeromes equation

1(7.86) + 4v = 80

- 7.86            - 7.86

4v = 72.14

/4     /4

v = 18.035 (round = 18)
