Step-by-step explanation:
(q and (not q or p)) = (q and not q) or (q and p) = false or q and p = q and p
(p and not (q and p)) = (p and (not q or not p)) =
= (p and not q) or (p and not p) = (p and not q) or false =
= p and not q
so, we have in total
(q and p) or (p and not q) = (p and q) or (p and not q).
this is p, because if p=false both brackets are false and therefore the whole expression is false. and if p=true, then one of the 2 brackets must be true, which makes the whole expression true.

Answer:
56
Step-by-step explanation:
The angle shown is a straight angle, so it is 180°.
x + 124 = 180
124 - 124 = x
180 - 124 = 56
x = 56
1/3x=20
1st step do the opposite of 1/3x to get it by itself. So you would do 1/3x *3/1 than you would do 3/1 *20. What you do to that side you do to the other.
2nd step 20*3=60
3rd You can check your answer by doing 1/3 *60=20
