∠A and \angle B∠B are vertical angles. If m\angle A=(2x+1)^{\circ}∠A=(2x+1) ∘
and m\angle B=(x+10)^{\circ}∠B=(x+10)
∘
, then find the value of x.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

cosine

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
