Answer:

Step-by-step explanation:

Unknown number = x

If twice the difference of x and 8 is 6:

2(x-8) = 6

2x-16 = 6

2x = 6 + 16

2x = 22

x = 22/2

x = 11

The vertices of a right triangle are (0, 0), (1, 0), and (0, 1).

Alchen [17]

Answer:

(3,3)

Step-by-step explanation:

Given

$Vertices: (0,0)\ (1,0)\ (0,1)$

$Scale\ Factor = 3$

Required

Determine which can't be any of the new vertices

First, we need to determine the new vertices:

$New\ Vertex = Scale\ Factor * Old\ Vertex$

For (0,0):

$New\ Vertex = 3 * (0,0)$

$New\ Vertex = (3 * 0,3 * 0)$

$New\ Vertex = (0,0)$

For (1,0):

$New\ Vertex = 3 * (1,0)$

$New\ Vertex = (3 * 1,3 * 0)$

$New\ Vertex = (3,0)$

For (0,1):

$New\ Vertex = 3 * (0,1)$

$New\ Vertex = (3 * 0,3 * 1)$

$New\ Vertex = (0,3)$

Comparing the calculated new vertices to the list of given options; (3,3) can't be any of the new vertices of the new triangle

Find the values of the variables ( I have five more of these if you will help me pls)

lord [1]

The angles of the figure are complementary, that is, the sum between them is equal to 90º.

Solving:
54º + 4xº = 90º
4xº = 90 - 54º
4xº = 36º
 $x = \frac{36^0}{4^0}$
$\boxed{\boxed{x = 9^0}}\end{array}}\qquad\quad\checkmark$

We have:
54º + 4.xº = 90º
54º + 4.(9º) = 90º
54º + 36º = 90º
90º = 90º (TRUE)

Answer:
The value of the variable is 9º
