Answer:

71º is measure of angle A

19º is measure of angle B

Step-by-step explanation:

complementary angles are angles that equal to 90º 

so let's add the terms (from angles A & B) and set them equal to 90º

3x+2 + x-4 = 90

4x -2 = 90

add 2 to both sides to get rid of the 2 on the left side and isolate our similar terms

4x = 92

divide both sides by 4

x=23

We're not done though, we must plug in our x value to Angle A terms and Angle B terms.

(3(23) + 2)º = measure of Angle A            (solve for both of them)

(23-4)º =  = measure of Angle B

3(23) + 2 =

3(23) = 69 (add the 2)

71º is measure of angle A

23-4 = 19º

19º is measure of angle B

double-check

71+19 = 90º

It works

Simplify −0.6(−6.3) answer??
Leno4ka [110]
3.78
All you need to do is plug in the numbers to your calculater, but since I'm guessing your in grade school, and they don't allow calculaters yet, you would need to understand that when two negatives multiply each other, they become positive, so you can just put 
    0.6
 x 6.3
---------
and then just multiply as usual (ignore the decimals for now)
and then you would get 378.
Now, what you would do is because there is too decimal points in the two numbers you are multiplying, you put them into 378, making it 3.78.]

I'm sorry if it was confusing, I hope it helped!

DOES ANYONE GET THIS? ):
KonstantinChe [14]

There is a given point (10,3) this shows that when the width (X) is 10, the height (Y) is 3.

On the left side of the graph, they show an equation for the height Hw as being the constant over w ( width).

Using the given point solve for the constant.

Replace Hw with 3 and w with 10:

3 = Constant/10

Solve for the constant by multiplying both sides by 10:

Constant = 3 x 10

Constant = 30

The answer is B.
