Please Explain How You Got The Answer .

RT = 11.2

Step-by-step explanation:

First, you have to find the central angle 360/3 ( 360 degrees divided by the amount of sides) = 120 then divide that by 2 = 60, so now you know that it's a 30 - 60 - 90 triangle. Then, you must use trigonometric ratios(SOH - CAH - TOA), in this case you need to use sin because you have the hypothenuse and your solving for x so you can use the opposite since you know your angle is 60. So then, Sin60 = x/9 ⇒ 9 * Sin60 = x. So, x = 7.7. Now, last but not certainly not least add the two segments together, 3.5 + 7.7 = 11.2

Result,

    Oof, I'm wrong. Sorry I tried.

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%

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3
