Question

the angles of a triangle are (x-30) (x-20) and (x-10) what is the value of x ???

Answer 1

Step-by-step explanation:

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

Answer 2

Step-by-step explanation:

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=
