Answer:

6.7 cm

Step-by-step explanation:

A+B+C=180°

55°+B+82°=180°

B=43°

Using the formulae

(Sin A)/a = (Sin B)/b

(Sin 55)/8 = (Sin 43)/b

b = [8(Sin 43)]/(Sin 55)

b= 6.7 cm

Help wanted can someone help me and give me a short understanding of this
Citrus2011 [14]
Y = 104°
z = 24

Angle y° and (5z - 44)° are linear pairs, meaning that the two measures together will add up to 180°.
To solve for z, know that (5z - 44)° and 76° are vertical angles, meaning that both angles are the same.
So simply set them equal to each other to find z:
5z - 44 = 76
5z = 76 + 44
5z = 120
z = 24

Now to solve for y, remember that since (5z - 44)° and 76° are vertical angles, they are the same, meaning you can denote (5z - 44)° as simply 76°. Like I said earlier, y and 76° are a linear pair so simply subtract 76 from 180 to find y:
180 - 76 = 104°

G(n) = 4n+5 f(n)= n^3+3n^2 find (g+f)(n)
Tpy6a [65]

Given:

The two functions are:

g(n)=4n+5

f(n)=n^3+3n^2

To find:

The function (f+g)(n).

Solution:

We have,

g(n)=4n+5

f(n)=n^3+3n^2

Now,

(f+g)(n)=f(n)+g(n)

(f+g)(n)=n^3+3n^2+4n+5

Therefore, the correct option is B.

0.329 is a rational number because the decimal stops. If it had continued on and on with no particular pattern, it would have been irrational. It can be a fraction too (329/1000)...

127.5 is a rational number because again the decimal ends. It can also be converted into a fraction which is another sign that it is rational (127 1/2)...

-89 is a rational number because negatives are rational numbers. It is also in the category of an integer, which means that is a rational number also...

The last one is a non-perfect square, which means no number squared could ever give you 101. When you solve for it, it is also a non-terminating decimal.
