Angle ABC is taken by a dilation witch enter P and Scale factor 1/3 to angle A'B'C'. The measure of angle ABC is 21∘. What is the measure of angle A'B'C'.

Step-by-step explanation:

Given

ABC dilated to A'B'C'

Required

Determine <A'B'C'

From geometry, we understand that dilation do not affect angles.

In other words, when ABC is dilated to A'B'C, the angles of A'B'C' retains the angles in ABC.

Using the above analysis:

Hence,

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
