176

Step-by-step explanation:

all the angles equal 360*

so 80 plus 55 = 135

so the equation is x + 49 + 135 = 360

combine like terms 49 plus 135 = 184

x+184=360 subtract 184 from both sides to get x = 176

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%
