<u>The angle based on the diameter is always right</u>

Then <ABC=90 and ∠BAC=∠ACB=45° ;  and ∠BCD=180-45=135 then                x=(180-135):2=22,5°

Need help with translation
sergij07 [2.7K]

Answer:

The translation rule will be: (x, y) → (x+3, y+9)

Step-by-step explanation:

As X'Y' is a translation of XY.

As the location of the vertix X is (-4, -9) and the coordinates of vertex Y is (-5, -5).

As X'Y'  be the vertices of the translated figure.

So, if we translate the segment XY +3 units in the x-direction and +9 units in the y-direction, i.e.

(x, y) → (x+3, y+9) = (-4+3, -9+9) = (-1, 0) = X'

and

(x, y) → (x+3, y+9) = (-5+3, -5+9) = (-2, 4) = Y'

so, the image X'Y' will have the X' vertice at the location (-1, 0) and Y' vertice at the location (-2, 4).

Therefore, the translation rule will be: (x, y) → (x+3, y+9)

Are the triangles similar? If so, explain why.<br> АД<br> 3462
Alchen [17]

<em>Greetings from Brasil...</em>

Just 2 equal angles are enough for the triangles to be similar .... The second triangle has the same angles as the first.

We know that the sum of the internal angles of a triangle is 180, so for the second triangle:

84,6 + 65 + X = 180

X = 180 - 84,6 - 65

X = 30,4   →   same angle as the largest triangle

So we have AA~ similarity

Which is a true statement about an exterior angle of a triangle
Harlamova29_29 [7]

Answer:

D

Step-by-step explanation:

The exterior angles are out of the triangle at all times and it adds up to make 180 with anyone of the inside angle of the triangle.

The pair also rests on the same flat/straight line and that makes a pair.

Therefore we can say that it is formed by a linear pair/group with one of the interior/inside angles of the triangle.

So, the correct answer would be D.
