Question

solve for x?

Answer 1

This

Answer 2

do you guys see the picutre?

Answer 3

which one? All of them?

Answer 4

The two functions represent two angels. The adding of 2 angles will either be 90 degrees or 180

Answer 5

i just need help on one of them to know had to do the rest

Answer 6

Ok, the first one has an angle of x-1, right? and another angle of 2x+1?

Answer 7

yes

Answer 8

Ok, then the measure of those 2 angles added together come to 90 degrees. So set up your problem like this:
(x-1)+(2x+1) = 90
which translates to
x-1+2x+1=90
3x=90
x=30

Answer 9

Does that one example help you to do the rest?

Answer 10

but what do you mean added together measure ike what measures

Answer 11

Those angles added together will equal 90 degrees, because the pic you showed us was a right angle, and right angles have a measure of 90 degrees.

Answer 12

angles are "measured". It's just a term.

Answer 13

ok yea then i do need help on the rest please if you dont mind

Answer 14

I don't mind at all! Let me take a peek at the second one!

Answer 15

ok thank you!!!

Answer 16

For the next one, you need to know that vertical angles are congruent. That means that angles that are "across" from each other are vertical and they have the same measure in degrees (they are equal). So your drawing actually means this:

Answer 17

ok so kinda like a square

Answer 18

Without trying to confuse you, let me just tell you that there are 2 ways in which to look at this and I will do it the simpler way, I hope!

Answer 19

All those angles will add up to equal 360 degrees. So we will do this:

Answer 20

5x+5x+50+50=360
10x+100=360
10x=260
x=26

Answer 21

ok wow that is is simple!

Answer 22

The next is like this:

Answer 23

If I told you that the 2 angles add up to 90 degrees, could you set up an equation for me?

Answer 24

If not, I can help...

Answer 25

yes i will try

Answer 26

Very cool.

Answer 27

(6x+4) + 26=90
6x=60
x=10

Answer 28

YES!!!!! Very cool!!

Answer 29

yess!!!!!

Answer 30

Now for the last one...it only looks scary....

Answer 31

yes thats for sure

Answer 32

Like with the one earlier with the vertical angles...the same thing applies. It looks like this:

Answer 33

And all those angles add up to equal 360. Can you set that up for me?

Answer 34

yes!

Answer 35

6x+4+6x+4+x+8+x+8
14x+24=360
14x=336
x=24

Answer 36

You are awesome...very very good!

Answer 37

Just remember the rules about vertical angles being equal to each other, and then remember that right angles add up to equal 90.

Answer 38

ok perfect you dont even understand the help you hve been

Answer 39

Well, thank you my dear. I'm a math teacher for a really good reason, then!!!

Answer 40

hahaha true true and a good one.... i feel bad asking but if you could, could you help me on this last page i have for this packet that i dont understand?

Answer 41

I would be happy to help.

Answer 42

thank you!!!! you are one of the few people on here that actually help...ok so let me take a picture

Answer 43

Ok, I'll be waiting with bated breath... ; )

Answer 44

hahaha...ok i posted a new question on is called help!!!!
