Please help me find the angle of these, Also show work if possible so i can use it for future lessons.

1. 68 , 2. 22, 3. 63, 4. 27, 5. 22

Step-by-step explanation:

Angles in a triangle add up to 180 degrees

180 - (68+ 90) = 22

Then to work out angle 1 you do 90 - 22 = 68

Angles on a straight line add up to 180 degrees

To find the angle next to 131 degrees

you do 180 - 131 = 49 degrees

49 + 68 + ? = 180

? = 63

90 - 63 = 26

90 - 68 = 22

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°
