Answer:

C) 140

Step-by-step explanation:

We can see from the diagram that mMEF + mDEM = mDEF because they share the same lines.

Therefore:

69x + 2 + 34 = 2 + 86x

Now we can solve this equation.

First we can eliminate the +2 from each side as they will cancel:

69x + 34 = 86X

And then rearrange to solve for x:

34 + 69x - 69x = 86x - 69x

34 = 17x

34/17 = 17x/17

x = 2

Now that we have the value for x, we can substitute it into the original equation:

mMEF = 69(2) +2

mMEF = 138 + 2

mMEF = 140

Therefore the correct answer is C) 140.

Hope this helped!

10) because of the alternative exterior angle theorem angle 2 is the same as angle 8 and because of the vertical angles congruence theorem angles 2 and 4 are also the same so if angle 2 is the same as both 4 and 8,
then x=5 because 4x+57 =77
subtract 57 from both sides and 4x=20
divide both sides by 4 and x equals 5

Use the information provided to write the equation of the circle Center: (10,-9) Point on Circle: (12,-13)
Zielflug [23.3K]

Answer:

(x - 10)² + (y + 9)² = 20

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

The radius is the distance from the centre to a point on the circle

To calculate r use the distance formula

r = √(x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (10, - 9) and (x₂, y₂ ) = (12, - 13)

r = \sqrt{(12-10)^2+(-13+9)^2}

  = \sqrt{4+16} = \sqrt{20}, hence

(x - 10)² + (y - (- 9))² = (\sqrt{20})², that is

(x - 10)² + (y + 9)² = 20
