hope it's helpful

please mark as brainliest

Answer 2

Answer:

x=140

Step-by-step explanation:

The First base interior angle is =180-70=110

The Second base interior angle is =180-60=120

there are 5 sides n=5

angle sum of a pentagon=(n-2)×180

=(5-2)×180

=3×180

=540

now

30+x+110+x+120=540   {sum of all angles of pentagon is 540}

260+2x=540

2x=540-260

2x=280

x=280/2

X=140

Value of x=140
