Answer:

Step-by-step explanation:

Because every triangle that can ever be made has three sides, you can open up the triangle so that it becomes a straight horizontal line. A horizontal line is also 180 degrees which is why this idea works with triangles.

This is because two angles are zero and top is a straight line, and a line is 180 degrees!

hopes this helps :)

Which choice shows the coordinates of C’ if the trapezoid is reflected across the y-axis?

padilas [110]

Answer:

Step-by-step explanation:

C is located at (5,3).

If you want to reflect this over the y-axis, you need to have the same distance that (5,3) is to the y-axis on both sides.

If you look at your graph you should see that (5,3) is 5 units a way from the y-axis so when you put it on the other side it should be 5 units a way also.

So the reflection will give you (-5,3)

Given RS = 6, ST = 3, and SL = 4, find SM.

NemiM [27]

A² + b² = c²
3² + 4² = c²
9 + 16 = c²
C² = 25
C = 5
so
SM = 5

Which ordered pale is a solution to the system of equations?

Softa [21]

Answer:

c) (-2, 1)

Step-by-step explanation:

3x - 3y = -9

2x + y = -3

-2x -2x

y = -2x - 3

3x - 3y = -9

y = -2x - 3

3x - 3(-2x - 3) = -9

3x + 6x + 9 = -9

9x + 9 = -9

- 9 -9

9x = -18

/9 /9

x = -2

y = -2x - 3

y = -2(-2) -3

y = 4 - 3

y = 1

(x, y) --> (-2,1)

Check your answer:

y = -2x - 3

1 = -2(-2) - 3

1 = 4 - 3

1 = 1

This statement is true

Hope this helps!
