Answer:

Step-by-step explanation:

We have the statement AB turns clockwise to coincide with BC.

= ABD + DBC

= 33.3° + 30.6°  

= 63.9°

Now we have the statement a point E is drawn directly opposite point C. B, E, and C are on the same straight line

EBC is a straight line, so sum of angles =180°

ABE + ABD + DBC = 180°

ABE + 33.3° + 30.6° = 180°

ABE + 63.9° = 180°

ABE = 180 - 63.1

ABE = 116.9° ....

Can You Help Me With numbers 6-8
k0ka [10]

Hello,

Your answers and explanations are below.

6 - 5xy

5 times the product of x and y. The product of x and y means to multiply. That is where we get this: xy. 5 times that product is where we add 5 to it and get this: 5xy.


7 - 4x

We get this because we know he gets $4 an hour. We just do not know how many hours he babysat. The hours is X and we multiply that by 4.


8 - 5.5

Take 8.3 and subtract 2.8 to find x. Once we do that we get 5.5, and that is X.


9 - We can't see the problem. It's cut off

Good Luck,

- I.A. -
