Question

What the answer to this please

Answer 1

The answer for x is 80°

Explanation:

60°+40°+x=180°

X=180°-60°-40°

X=80°

Answer 2

It’s 80 because the sum of all the angles should be 180 so you’d subtract the angles u already have which is 60+40=100 and then u subtract that from 180 and u get 80

X=80
