Answers:
mAE = 78°
mABD = 206°
mDA = 154°
mBCE = 255°
mECA = 282°
--------------------------------------------
Explanation:
The total arc measure of a circle is 360.

This circle shows that mDE has the same arc as mDC. mDC's arc will equal 76.

To find mAE, add all the known arc values, set mAE to x, and set the equation equal to 360.

27 + 103 + 76 + 76 + x = 360

Combine all like terms.

27 + 103 = 130
76 + 76 = 152
130 + 152 = 282

282 + x = 360

Subtract 360 from both sides to get x by itself.

x = 78

The arc measure of mAE is 78.


Now we can find all of the arc values.

mAE = 78°

mABD = measure of mAB + mBD
27 + (103 + 76) = 27 + 179 = 206

mABD = 206°

mDA = mDE + mEA

76 + 78 = 154

mDA = 154°

mBCE = mBC + mCD + mDE

103 + 76 + 76 = 179 + 76 = 255

mBCE = 255°

mECA = mED + mDC + mCB + mBA

76 + 76 + 103 + 27 = 152 + 130 = 282

mECA = 282°

Triangle ABC has A(-3,6),B(2,1), and C(9,5) what the length of side AB? What the length BC what the length AC and what ABC
vovikov84 [41]

Answer:

<em>AB = 5√2</em>

<em>AC = √145</em>

<em>BC = √65</em>

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

For AB A(-3,6),B(2,1),

AB = √(2+3)²+(1-6)²

AB = √(5)²+(-5)²

AB = √25+25

AB =  √50

<em>AB = 5√2</em>

For AC A(-3,6) and C(9,5)

AC = √(9+3)²+(5-6)²

AC = √(12)²+(-1)²

AC = √144+1

<em>AC = √145</em>

For BC B(2,1), and C(9,5)

BC = √(9-2)²+(5-1)²

BC = √(7)²+(4)²

BC = √49+16

<em>BC = √65</em>

<em></em>

<em>Since All the sides are difference, hence triangle ABC is a scalene triangle</em>

8. Solve the system using substitution. Show all work. (3 points)
Minchanka [31]
Ok. first you have to pick x or y or whatever variable you have and the number multiplied with it has to be the same in each equation but one has to be positive and one negative.
lets pick x

y=-2x+6
3y=x-3/ *2

so the x are positive and negative we have to multiply the equation with 2

y=-2x+6
6y=2x-6

now you have to add the equations. you do that by adding each side of the equatins together like this:

y+6y=-2x+6+2x-6 the x will cancel out

7y=0
y=0

now just go back to one of the previous equations and put the y in it.

0=-2x+6
2x=6
x=3

here you go
