What is the value of p?

50degrees

subtract 180with140and with 90 then add

50˚ "D"

Step-by-step explanation:

All you have to do is subtract  140 by 90

Your equation should look like this: 140-90

20%

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
