70% of the woodland in the county is native woodland. This means there are 350km² of native woodland in the county. Work out the area of woodland in the county that is not native woodland?

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

Ithink the answer is: it is likely.
