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
