Answer:
angle a = 20 degrees
angle b = 160 degrees
angle c = 15 degrees
angle d = 75 degrees
Step-by-step explanation:
Every straight angle equals 180 degrees, and every right angle is half of that (90 degrees). This is helpful to remember during geometry- every unknown angle is part of either a right or a straight angle. Honestly, if you look carefully enough, most of the answers are supplied in opposite angles.
Hope this helps! If not, let me know! :)
Answer:
460256
Step-by-step explanation:
35900 books equal to 7.8% of all copies sold
<u>Total number of books:</u>
- 7.8% = 35900
- 100% = ?
- 35900*100/7.8 ≈ 460256
<u>Answer is</u> 460256 in whole numbers
The value of 5 in 56 is 50.
Number 3.
opens up
vertex (1,2)
idk maybe because it is on the right side. its positive
number 4.
opens up as well
Vertex (-2,0)
no because it is negative and on the left. Idk just a guess for this one
If I'm correct, it should be y = 4x + 2.
