Answer:
m∠p = 131
Explanation:
to find this we can use the exterior angle theorem
this states that the two inner angles added together equals the opposite outer angle
so
we can start with a
we must find the inner angle a
180 - 162 = 18
that is the inner angle of a
now we must use the exterior angle theorem to find p
a + p is 149
a + p = 149
substitute 18 in
18 + p = 149
now subtract 18 from both sides
p = 131
that is your answer
