What’s the items number. ? When rounding everything in front of the decimal find the place value it wants you to round then if it’s 5 or below round the the lowest whole number. If it’s behind a decimal you would do the same thing. It’s the number is higher than 5 round it up.

End point - points on either end of a line segment or on one end of a ray.

Ray - A part of a line, with one endpoint, that continues without end in one direction

Line - a line of points that extends infinitely in two directions

Collinear - points that lie on the same line

Midpoint - A point that divides a segment into two congruent segments

Plane - A flat surface on which a straight line joining any two points would wholly lie.

Help me with this math question gr 8 math please

Answer:

C = 112, A = 150, D = 30, B = 38

Step-by-step explanation:

I solved C first using:

30+38+c = 180 (angles along a straight line should add up to 180 since a whole circle is 360)

I solved A by looking across from C.

Angles on opposite sides should mirror each other but A includes 38* + C

Just by doing 112 + 38 you get 150.

I solved D by looking at 30*, alternative interior angles are the same so D is 30*.

I solved B by taking C (112) and D (30) and adding them together and subtracting from 180.

Interior angles of a triangle should all add up to 180,

112 + 30 + B = 180

From this I got that B was 38.

Alternatively you can find this out by looking at the 38 degrees, corresponding congruent angles are always the same.

I suggest reviewing this angles sheet if you're ever stuck in the future.
