Answer:

21

Step-by-step explanation:

The sum of degrees in a triangle is 180, so we have:

3x+100+x-4=180

add 4 on both sides

3x+100+x=184

subtract 100 on both sides

3x+x=84

Combine like terms

4x=84

84/4 = 21

Answer:

x=21

Step-by-step explanation:

x-4+100+3x=180

(180 are the degrees of a triangle added together)

subtract 100 on both sides

x-4+3x=80

simplify like terms

4x-4=80

add 4 to both sides

4x=84

divide 4

x=21

gayaneshka [121]

Answer:

A. yes

Step-by-step explanation:

The contestant has a 60% chance of winning because they could either spin 1, 3, or 5.

However, unless there's another player who can only spin evens, it's not fair, because the contestant who spins odds has a 60% chance, while this player will only have a 40% chance.
