Answer:

choice 2) angle DOC = 145 degrees

Step-by-step explanation:

angle ABD = 1/2(30 degree arc) = 15 degrees because of the inscribed angle theorem.

angle AOB = 180 - 20 - 15 = 145 degrees

angle DOC  = angle AOB because it is a vertical angle to 145 degrees.

Talja [164]

Answer:

Robyn and Vladimir both are correct.

Step-by-step explanation:

Vladimir says that the equation of the line the passes through points (-5, -3) and (10,9) is y = \frac{4}{5} x + 1

Let's find the equation of line

Slope of the line passing through ( -5, -3 ) and (10, 9 )

m=\frac{y-y'}{x-x'}=\frac{9+3}{10+5}=\frac{12}{15}=\frac{4}{5}

So equation will be y = \frac{4}{5}x + c

Since the line passes through (-5, -3)

so (-3) = \frac{4}{5}x (-5) + c

(-3) = -4 + c

c = -3 +4 = 1

So equation should be y = \frac{4}{5}x +1

Therefore, Vladimir is correct.

Robyn says this line is passing through  (-10,-7) and (-15, -11)

Slope m=\frac{y-y'}{x-x'}=\frac{-11+7}{15+10}=\frac{-4}{-5}=\frac{4}{5}

equation is y = \frac{4}{5}x + c

Since this line passes through (-10 -7)

so (-7) = \frac{4}{5}x (-10) + c

-7 = -8 + c ⇒ c = 8 - 7 = 1

Equation of the line will be y = \frac{4}{5}x + 1

So Robyn and Vladimir both are correct.
