In a translation the angles and side lengths of the figure remain the same.  Only the position changes.

D is correct.

Answer:

The side lengths remain the same, and the position of the figure changes.

Step-by-step explanation:

A translation is a slide of a figure.  A figure can be slid vertically, horizontally or diagonally.

Think of sliding a game board across a table.  The lengths of the sides of the board do not change; the angles formed by the sides of the board do not change; and the way the board is turned does not change.  This means the only correct option would be the last one.

Measure of the interior angles of the triangle
scoray [572]

Answer:

Angle A: 45, Angle B: 110, and Angle C: 25.

Step-by-step explanation:

A triangle is 180 degrees total. One angle is 25 degrees. 180- 25 leaves us with 155 degrees. We know that one angle is more than 65 degrees. 155-65 is 90. 90/2 is 45. Therefore, x= 45. Angle A: 45, Angle B: 110, and Angle C: 25. We can double check our work by adding 45+110+25= 180

Find the missing length. The triangles are similar.
hodyreva [135]

Answer:

182

Step-by-step explanation:

First, we can say that ∠ACB and ∠BCF are opposite angles because they are not next to each other and are formed by intersecting lines. Therefore, ∠ACB = ∠BCF

Next, angles correspond with the side opposite of it. This means that, for example, ∠ACB corresponds with line AB and ∠BCF corresponds with line BF. Because ∠ACB and ∠BCF are equal and the triangles are similar, we can say that their corresponding sides have a ratio with each other. Similarly, ∠CAB corresponds to CB, ∠ABC corresponds to AC, ∠CWV corresponds to CV, and ∠CVW corresponds to CB.

Because the triangle CVW is isosceles, we can say that the angles whose corresponding sides are equal are equal as well, so ∠CAB = ∠ABC and ∠CVW = ∠CVW. Next, because ∠ACB and ∠BCF are equal and correspond to each other, and the other two angles in each triangle are equal to each other, we can say that the other two angles must be equal. Another way of putting this is like this:

Say that x = ∠CAB. Then,

∠CAB + ∠ABC + ∠ACB = 180

x + x + ∠ACB = 180

2x + ∠ACB = 180

subtract ∠ACB from both sides

180 - ∠ACB = 2x

Similarly, if y = ∠CWV,

180 - ∠WCV = 2y. Therefore, 2y=2x and y=x, so ∠CAB = ∠ABC = ∠CWV = ∠CVW.

Given this, we can say that sides CV and CW correspond with BC and AC. This means that the ratio between, for example, CV and BC is equal to the ratio between CW and AC. Therefore,

CV/BC = CW/AC

84/182 = 84/?

Filling in the blank, 84/182 is equal to 84/182, so ? = 182

There are 60 students in a class. Among them,20 students are girls .Find the ratio ofa. Boys and total studentsb. girls and tota
valina [46]

Answer:

Girls to boys = 1:2

Girls to students = 1:3

Boys to students = 2:3

Step-by-step explanation:

So, let's subtract the number of girls from the number of students in the class:

60 - 20 = 40

This means that for every 20 girls there are 40 boys in the ratio of girls to boys:

20:40

This can be simplified down by factoring, here we can divide by 20:

(20 ÷ 20) : (40 ÷ 20)

1:2

So the ratio of girls to boys is 1:2

The ratio of boys to students can be calculated via:

40:60

This can be simplified by dividing by 20 again:

(40 ÷ 20) : (60 ÷ 20)

2:3

So the ratio of boys to students is 2:3

The ratio of girls to students can be put in a ratio of:

20 : 60

This can be simplified down by dividing by 20:

(20 ÷ 20) : (60 ÷ 20)

1:3

So the ratio of girls to students is 1:3

Hope this helps!
