3. What is the scale factor of Figure B to Figure A?
xxMikexx [17]

Answer:

2.5

Step-by-step explanation:

From the diagram, figure B was enlarged to obtain figure A.

The two figures are therefore similar.

The corresponding sides are in the same proportion. That constant value of the proportion is called scale factor.

It is given by:

k =  \frac{image \: length}{corresponding\:object \: length}

Figure B is the image of A

k =  \frac{10}{4}  =  \frac{25}{10}  = \frac{21.5}{8.6} =   2.5

Therefore the scale factor is 2.5

Determine which characteristics are true of vertical angles
liq [111]

Answer:

1, 2 and 4 option - Yes

3 option - No

Step-by-step explanation:

<u>Definition: </u>Vertical angles are the angles opposite each other when two lines cross.

By the definition options

  • they are formed by intersecting lines,
  • they are opposite to each other

are true.

Vertical Angles Theorem states that vertical angles are congruent. Thus, option

  • they are congruent

is true.

Option

  • they are always supplementary

is false, because supplementary are angles that add up to 180°, but vertical angles can have different measures which do not add up to 180°.
