Question

019) If the angles of a triangle are (x-10)". (2x+10) and (6x), then the value 1 point of x is O 10 degree 0 20 degree O 30 degree O 40 degree​

Answer 1

Answer:

The x+10,2x−30,x are angles of triangle

By angle sum property

Sum of all angles is 180

x+10+2x−30+x=180

4x−20=180

4x=180+20

4x=200

x=

4

200

x=50
