Answer:

X=20

Explanation:

the total angle degree of a triangle is always 180 so we have two point 100 and 40 add those and you get 140 so you have 40 left but that angle says 2 X so 2x is 40 so ÷ 2 to get 1x which is 20

Answer:

x = 20

Explanation:

first, you would take all of the angles and add them up to 180

2x+40+100=180

second, we combine like terms

2x+140=180

third, we solve for x

2x+140=180

-140 -140

2x=40

x=20

i hope this helps!
