Answer:

m∠B = 54°

Step-by-step explanation:

Note: Complementary angles add up to 90°

Thus, m∠A and m∠B must add up to 90.

We can then write this equation.

x - 15 + x + 3 = 90

Simplify.

2x - 12 = 80

Add 12 to both sides.

2x = 102

x = 51

m∠B is (x + 3) , so m∠B = 51+ 3 = 54°

Just in case, let's double check. Plug 39 for x into m∠A to get

m∠A = 51 - 15 = 36

Then, plug the angle measures in.

36 + 54 = 90

90 = 90

Thus, the answer is correct.

I hope this helps! Feel free to ask any questions! :)

Angle B = 54°

Step-by-step explanation:

complimentary means they add up to 90

54 + 36 (angle A) = 90

also x= 51

Write the first five terms of the sequence in which the nth term is
ziro4ka [17]

Answer:

C) 2,6,24,120,720

Step-by-step explanation:

Here the n-th term An = \frac{(n +2)!}{n + 2}

A1 is the first term

A1 = (1 + 2)!/(1 + 2)

= 3!/3

A1 = 2

A2 is the second term

A2 = (2 +2)!/(2 +2)

= 4!/4

A2 = (1*2*3*4) /4

A2 = 6

A3 is the third term

A3 = (3 + 2)!/(3 +2)

A3 = 5!/5

A3 = 24

A4 is the fourth term

A4 = (4 + 2)!/(4 + 2)

A4 = 6!/6

A4 = 120

A5 is the fifth term

A5 = (5 + 2)!/(5 +2)

A5 = 7!/7

A5 = 720

Answer: C) 2,6,24,120,720

Thank you.

Do the following points represent a function? (0,2) (1,4) (0,4) (3,9) (5,8)​
photoshop1234 [79]
<h3>Answer: No, this isn't a function.</h3>

Why not? Focus on the two points (0,2) and (0,4)

We have the x value x = 0 show up twice. Any time x repeats itself like this, it leads to "not a function" as the result.

In other words, the input x = 0 leads to multiple outputs y = 2 and y = 4 at the same time. A function is only possible if every x input leads to exactly one y output.

If you are a visual learner, then plot all of the points on the same xy grid. Then notice how (0,2) and (0,4) fail the vertical line test to show we don't have a function.

Side note: The y values can repeat themselves in a function.
