Question

if the outer angle at the three vertices of a triangle are (2x+30)°, (3x-10)°, and 100°. what is the value of x?​

Answer 1

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

Hope it helps
