The vertices of a triangle are a(7, 5), b(4, 2), and c(9, 2). what is m`/_abc`?

So first you have to know the distance between those three points:

AB= √18

BC= 5

AC=√13

Then use Trigonometric function to find m/_ABC:

CosB=(a^2+c^2-b^2)/2ac

cosB={(√18)^2+(√13)^2-5^2}/2√18√13

The Answer should be m/_ABC=30

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

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%
