What is the length of BC⎯⎯⎯⎯⎯ ?<br><br><br> Enter your answer in the box.
Rudiy27

Answer:

  \overline{\text{BC}}=\boxed{22}

Step-by-step explanation:

The angle marks mean those angles have the same measure. That means the sides opposite them have the same measure, so ...

  2x -24 = x -2

  x = 22 . . . . . . . . . add 24-x

The length of BC is x, so is 22.

BC = 22

What is the equation of the line that contains the point (-1, 4) and has a slope of 3?
sertanlavr [38]

Let's write the equation with formula:-

\boxed{ \sf \: formula : y -y_{1} =  m(x -  x_{1})}

Where,

  • x1 is -1 and y1 is 4 and m is 3

\tt \: y - 4= 3(x - ( - 1))

\tt \: y  - 4 = 3(x + 1)

\tt \: y  - 4 = 3x + 3

\tt \: y = 3x + 3 + 4

\tt \: y = 3x + 7

<em>Thus, The correct choice is option C!!~</em>
