Which best compares the pair of intersecting rays with the angle
madam [21]

Answer:

C)The rays extend infinitely, and the angle is made by rays which have a common endpoint

Step-by-step explanation:

A ray is a line segment having one end point while extending in the other/opposite direction

An angle is made by two lines(rays) with common end point (vertex)

So when an angle is formed by the pair of intersecting rays the following options are ruled out  

A) rays cannot have two end points

B) As rays extends infinitely in one direction, so having number of points is wrong

D)angles do not have lines

the following is best explanation is C

The rays extend infinitely, and the angle is made by rays which have a common endpoint !

If the operation ⊕ is defined by p⊕q = square root of p^2 +q^2, What is 8⊕6? <br><br> Please Explain
Elanso [62]

8⊕6 is 10

Step-by-step explanation:

We will use the substitution method to solve this problem

∵ The operation ⊕ is defined by p⊕q = \sqrt{p^{2}+q^{2}}

∵ You want to find 8⊕6

- Then do these steps:

  • Substitute p by 8
  • Substitute q by 6
  • Calculate the square root of 8² + 6²

∵ p = 8

∴ p² = 8² = 64

∵ q = 6

∴ q² = 6² = 36

∵ p⊕q = \sqrt{p^{2}+q^{2}}

- Substitute p by 8 and q by 6 in the rule above

∴ 8⊕6 = \sqrt{(8)^{2}+(6)^{2}}

- Substitute 8² by 64 and 6² by 36

∴ 8⊕6 = \sqrt{64+36}

∴ 8⊕6 = \sqrt{100}

∵ \sqrt{100}=10

∴ 8⊕6 = 10

8⊕6 is 10
