Can someone help me with this one ??

s344n2d4d5 [400]

Answer:

Measure angle B = 65 degrees AB = 34 AC = 30

Step-by-step explanation:

Triangle Sum Theorem: 180 - 90 - 25 = 90 + 25 + 65 = 180

Tangent 25 = 16/x

AB = 34

Pythagorean Theorem Equation:

$b =[]\sqrt{34^{2} - 16^{2}}= \sqrt{900}= 30$

AC = 30

Find A={a,b,c} then find A*A.

Alenkasestr [34]

Assuming you want to do a cartesian product, then you basically form items (x,y) such that x is in set A, and y is in set A

More generally, A * B will consist of items of the form (x,y) such that x is in A and y is in B. However, we have B = A.

So,

A * A = {

(a,a), (a,b), (a,c)

(b,a), (b,b), (b,c)

(c,a), (c,b), (c,c)

}

I broke things up into separate rows to show that we can form a 3x3 table. Each row is a different x value from the set {a,b,c}. Each column is a different y value from the set {a,b,c}

In my opinion, this helps organize things much better than rather have it all on one single line like this

A * A = { (a,a), (a,b), (a,c), (b,a), (b,b), (b,c), (c,a), (c,b), (c,c) }

which in all honesty looks like a bit of a cluttered mess.

1/3(9−6m)+1/4(12m−8)

Sladkaya [172]

Hello there!

They are asking you to simplify it. So, let me help you out..

$\frac{1}{3}(9-6m)+ \frac{1}{4}(12m-8)

Use the distributive property 

$
(1/3)(9) + (1/3)(-6m) + (1/4)(12m) + (1/4)(-8)
=3 - 2m + 3m - 2
= m + 1

Best of luck with your studies!
