The line contains point (2, 0) and (-5, 4).
y - 0 = (4 - 0)/(-5 - 2) (x - 2)
y = -4/7 (x - 2)
7y = -4(x - 2)
7y = -4x + 8
4x + 7y = 8
The shape that is generated is a Cone.
A triangle, when rotated about one of it's side will generate a solid in a form of a Cone. The cone could be a hollow one or a solid filled one, depending on the properties of the triangle being rotated.
Answer:
Hello! answer: 9
Step-by-step explanation:
Assuming this is a complementary angle (meaning it will add up to 90 degrees)
5 × 9 = 45 45 + 15 = 60 60 + 30 = 90 therefore x = 9 Hope that helps!
Answer: Option D.
Step-by-step explanation:
To solve this exercise you must keep on mind the Angle at the Center Theorem.
According to the Angle at the Center Theorem, an inscribed angle is half of the central angle.
Therefore, given in the inscribed angle m∠BAC=35°, you can calculate the central angle m∠EFD as following:
![BAC=\frac{EFD}{2}](https://tex.z-dn.net/?f=BAC%3D%5Cfrac%7BEFD%7D%7B2%7D)
- Solve for EFD.
![EFD=2*BAC](https://tex.z-dn.net/?f=EFD%3D2%2ABAC)
- When you substitute values. you obtain:
![EFD=2(35\°)\\EFD=70\°](https://tex.z-dn.net/?f=EFD%3D2%2835%5C%C2%B0%29%5C%5CEFD%3D70%5C%C2%B0)
