Question

What is the measure of angle p?

Answer 1

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°

Answer 2

130

Explanation:

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
