Answer:
130°
Explanation:
p and the 50° angle form a straight line/straight angle, meaning they are supplementary.
Supplementary angles add to 180°.
p+50=180
p=130
130
angles formed by a straight line add up to equal 180°
Thus, 180 = 50 + p
180 - 50 = 130
50 - 50 cancels out
we're left with p = 130
