Here are the following items to be arranged:
<span>- protostar
- supernova
- contracting cloud of gas and dust
- main-sequence O star
- red supergiant
- neutron star</span>
Given:
WXYZ is an isosceles trapezoid. WY=8x-3 and ZX=19.
To find:
The value of x.
Solution:
We know that the diagonals of an isosceles trapezoid are equal. So,
![WY=ZX](https://tex.z-dn.net/?f=WY%3DZX)
![8x-3=19](https://tex.z-dn.net/?f=8x-3%3D19)
Add 3 on both sides.
![8x-3+3=19+3](https://tex.z-dn.net/?f=8x-3%2B3%3D19%2B3)
![8x=22](https://tex.z-dn.net/?f=8x%3D22)
Divide both sides by 8.
![x=\dfrac{22}{8}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B22%7D%7B8%7D)
![x=2.75](https://tex.z-dn.net/?f=x%3D2.75)
Therefore, the correct option is B.
Answer:
x = 3.5
Explanation:
The chords are the same length, so are the same distance from center:
3x +1 = x +8
2x = 7 . . . . . . subtract x+1
x = 3.5 . . . . . divide by 2
