If triangle XYZ’s points are X (-2, 1), Y (-4,-3), and Z (0,-2) what are the new coordinates of X’, Y’, and Z’ if the triangle i

8090 [49]

Answer:

The coordinates of image are X'(-3,4), Y'(-5,0) and Z'(-1,1).

Step-by-step explanation:

The vertices of triangle XYZ are X(-2,1), Y(-4,-3) and Z(0,-2).

It is given that the triangle translated by rule

$(x,y)\rightarrow (x-1,y+3)$

The coordinates of image of XYZ are

$X(-2,1)\rightarrow X'(-2-1,1+3)$

$X(-2,1)\rightarrow X'(-3,4)$

$Y(-4,-3)\rightarrow Y'(-4-1,-3+3)$

$Y(-4,-3)\rightarrow Y'(-5,0)$

$Z(0,-2)\rightarrow Z'(0-1,-2+3)$

$Z(0,-2)\rightarrow Z'(-1,1)$

Therefore coordinates of image are X'(-3,4), Y'(-5,0) and Z'(-1,1).

One triangle has an angle of 81 degrees and the corresponding angle of the other triangle is 2x - 5 degrees, find the value of x

Delicious77 [7]

Answer:

$x=43$

Step-by-step explanation:

Corresponding angles are equal. It is implied that the two angles referred to in the triangles are equal, otherwise they should not be labelled as corresponding.

Therefore, we can set both equations equal to each other:

$2x-5=81^{\circ}$

Add 5 to both sides:

$2x=86$

Divide both sides by 2:

$x=\frac{86}{2}=\boxed{43}$

Find the distance between the points (3,9) and (9, 1).

mrs_skeptik [129]

Answer:

Distance is equal to 10.

Step-by-step explanation:

Use the distance formula: d=√((x_2-x_1)²+(y_2-y_1)²)

d = √(9-3)^2 + (1-9)^2

d = √(6)^2 + (-8)^2

d = √36 + 64

d = √100

d = √10

Hope this helps :)
