Answer:
Look at the image.
Step-by-step explanation:
If 12 is 24%, then half of the percent is the actual number.
36% = 18
24% = 12
18% = 9
22% = 11
18 + 12 + 9 + 11 = 50

Supplementary angles = Angles that add up to 180°.
∠5 + ∠7 = 180° ← supplementary angles
∠1 = ∠5
Since ∠5 + ∠6 = 180°
⇒ ∠1 and ∠6 will also be 180° . ← supplementary angles

Answer: ∠5 + ∠7 (Answer D) and ∠1 + ∠6 (Answer A)

First you have to write the equation...(x+7)5=30
then solve; so, x= -1
Answer:
Three non-collinear points determine a plane.
Step-by-step explanation:
This statement means that if you have three points not on one line, then only one specific plane can go through those points. The plane is determined by the three points because the points show you exactly where the plane is
Answer:
p is perpendicular to n. Proved.
Step-by-step explanation:
See the diagram attached.
Let us assume that mm' and nn' are two straight lines parallel to each other and pp' is a transversal.
It is given that pp' is perpendicular to mm' i.e. ∠po'm = 90°
Now, since mm'║nn' and pp' is a transversal, so, ∠pon = ∠po'm = 90° {Those are corresponding angles}
So, pp' is also perpendicular to nn'. {Proved}
