-(-2x-6y=-16)

2x+6y=16
4x-6y=-58

Y's cancel out, then add the rest

6x=-42

divide both sides by six

x=-7

plug x into any previous equation

2(-7)+6y=16

-14+6y=16

6y=30

y=5

What is the value of x ? (Make sure you give the value of x !!!!)

DochEvi [55]

Answer:

The value of x is 20 degrees.

Step-by-step explanation:

The three angles of a triangle must equal 180 degrees.

100 + 40 + 2x = 140 + 2x

180 - 140 = 40 (goal)

2(x) = 40

2(20) = 40

A) 20 degrees

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
