Question

The angles of a triangle are x, x+10 and x+20. The value of x is

Answer 1

Answer:

x+(x+10)+ (x+20). =180° (angle sum property)

3x+30=180°

3x= 180°-30°

3x=150°

x = 150°/3

x = 50°

Answer 2

Hope this will help you remember to put the x+10 gives this answer and all that stuff because it is the most important part
Then at last write that the sides of angles are 70,60 and 50
