16. ∠2 = 53° because it is supplementary.
- You are given the measurement of ∠1, which is 128°. From the picture you can see that ∠1 and ∠2 combined equal 180° (they are supplementary angles).
- So to find ∠2, simply subtract 128° from 180°. The answer is 53°.
------------------------------------------------
17. 12° because it is vertical.
- Vertical angles, like 48° and 4x in the image, are always equal.
- So if 4x = 48°, then you can divide both sides to get x = 12°.
Coplanar lines<span> are </span>lines<span> that lie on the same plane. Picture a giant sheet of paper. Whatever </span>lines<span> are drawn on that sheet of paper will be </span>coplanar<span> because they are lying on the same plane, or the same flat surface.Or two strips of bacon on a frying pan would be coplanar lines lines that are,on the same plane</span>
Answer:
Step-by-step explanation:
First, you need to find the GCF of both denominators.
That would be 21.
You would need to multiple the 7 in 4/7 by 3, to get to 21. That means you would also have to multiply 3 by the 4. You should get 12/21.
Do you same thing to 1/3.
After that you should get the 2 factions, 12/21 and 7/21
12/21 + 7/21 = 19/21
There isn't anyway to simplify it, meaning the final answer is 19/21.
Y = -5 / 4 x 3
-5 / 4 = -1.25 x 3 = -3.75
y = - 3.75
