Question

Do it with eplanation

Answer 1

Answer:

x = 50

Step-by-step explanation:

he sum of traingle is 180°

so,

X+10 + X+20 + X = 180

3X + 30 = 180

3X = 180 - 30

X = 150/3

X = 50

Answer 2

Answer:

50 degree, 60 Degree, 70 degree

Step-by-step explanation:

Using angle sum property, we get

x + (x+10) + (x+20) = 180 degree

3x + 30 = 180

3x = 180-30

3x = 150

x = 150/3

x = 50 degree

Therefore,

x = 50 Degree

x+10 = 50 + 10 = 60 Degree

x+20 = 50 + 20 = 70 degree
